Jeanne a little more mean

3rd Hurricane Hits Polk County; CREC damage list grows;
Citrus losses mount around the state

A record third hurricane ,
- Jeanne swept through
Polk County on Sept. 26,
causing more damage to
eastern and central Florida
just weeks after being hit by
Hurricane Frances. This L
was the fourth hurricane to
hit Florida this year. |
Hurricane Jeanne caused
more damage to CREC
facilities than the previous
Hurricanes Charley (Aug.
13) and Frances (Sept 4)..
Ben Hill Griffin, Jr. Citrus

has roof damage and was
flooded with an inch ofwater. Numerous damage
reports included greenhouse and screenhouse
damage, ceiling and roof leaks, floods and other
related problems. Damage to the Center's citrus
included more fruit loss and damaged trees.
Researchers are in the process of determining
damage to experimental plots around the state.
Power was restored to the eastern part of the
Center after four days, and to the rest of the
Center after five days. Generators were set up
for freezers, the telephone system and other
critical items.

Students Tour U.S.
Dr. Bill Castle hosted Dr. Hubert Werner
and a group of biology, horticulture,
landscape and soil science students from
Germany on a citrus tour to CREC on Sept.
29 (photo below). The visit was part of a
southeastern U.S. tour for the students,
which included visits to other UF/IFAS
Research and Education Centers and various
agricultural operations (they stayed in St.
Augustine during Hurricane Jeanne). Dr.
Monica Lewandowski provided an overview
of the Center and Dr. Castle took the group
to a tour of the Water Conserv II site in
Orlando, where reclaimed water (highly
treated wastewater) is used to irrigate citrus,
a golf course and other crops. The group
also visited with representatives of Florida
Citrus Mutual and the FDOC in Lakeland.

Meet... CREC's Information Services
by Meredith J. Morton; Photos by Gretchen Baut
CREC may be best known for our citrus programs, but it is the work
behind the scenes that helps to hold the Center together and keeps it
functioning properly. Much of this work is performed by Mike Armstrong,
Allan Burrage and Gary Wilhite of CREC's Information Services Department
Although their offices are located in the Ben Hill Griffin, Jr. Citrus Hall,
the ISD group spends much of their time working hands-on with various
information services systems out of the office.
Mike, Allan and Gary are the talented, knowledgable and hard-working
men who help keep CREC's computer, network and electrical systems at
CREC work properly. Each member of the ISD group has a unique
background that has helped to make them great assets to CREC.

Mike Armstrong is the working
manager in the ISD group and has been at
CREC since June 1998. As working
manager of ISD, Mike said he basically
handles all the paperwork and on the
technological side, works with the network
systems and CISCO (telephone)
equipment. He also conducts research to
help guide CREC on current and future
computer issues, whether it be an
immediate problem with spam and
computer viruses, or looking ahead to new
network technology.
Mike's history with computers and networking goes back
nearly half a decade to 1957, when he said he saw his first computer
in a computer lab at the University of Rochester, New York. Perhaps
it was love at first sight, but he says seeing a computer for the first
time inspired him to take a part time job in the University's computing
center. This position became full-time in 1962, when he graduated
with a bachelor's degree in electrical engineering.
After working at the University of Rochester for several years,
Mike decided to move to a warmer climate and moved to Miami in
1969, where he was the senior director of system support for the
Ryder truck system for 11 years. This position involved traveling
to instruct other employees how the manage their computer systems.
During his years at Ryder, Mike was also the chairman of an IBM
user group council.
Following his position at Ryder, Mike, who has a pilot's license,
worked for Fantasy of Flight owner Kermit Weeks as an aircraft
mechanic and antique airplane restorer. While working in Polk
City, Mike said he would see CREC on hiss way to work and was
curious about what was done at the center.
It was 1998 before Mike learned about CREC. By this time, he
had trained for another career as a Microsoft Systems Organizer
and became interested in the microprocessor/microcomputer world.
In the five years Mike has been at CREC, he said he has really
enjoyed his work and has been blessed with good employees.

Allan Burrage is the newest member of the ISD group,
having been at CREC for slightly more than a year.

From left to right, Allan Burrage, Mike Armstrong
(seated) and Gary Wilhite keep CREC's computer,
electronic and telephone systems running.

A Georgia native from a family of I
'tree-climbers,' Allan started his career A
as a professional lumberjack, but a 1992
tractor accident injured his back and
promtped him to look for another career.
Allan's interest in computers developed
whenhe was askedto baLibh i" friend's
Allan moved to Florida, where he
attended Ridge Technical Institute in 1997
and studied software application
support. After finishing at Ridge, Allan ...
was recruited by Gateway, where he spent five years in Kansas City
doing elite technical support. While at Gateway, he managed
technical teams and gained training on servers and networks.
In 2003, CREC hired Allan to maintain the servers and make
sure they don't develop problems. He also does high-end user
support. Since he's been at CREC, the networks have been upgraded
to 2003, evolving to the point it is self-reliant, and the e-mail server
has been updated. Allan's areas of specialty include server
management, e-mail server exchange and network implementation.
Allan is currently attending Polk Community College (PCC)
through UF's Employee Education Program and plans to pursue a
bachelor's degree in computer science at either USF or UCF.
Allan enjoys spending time with his wife Anne and their three
sons, Steven, 14, Daniel, 10, and Thomas, 9. He is a member of a
historical miniature society and maintains a few small servers on the
side. Allan is also involved in his church and enjoys movies.

Gary Wilhite has been working
at CREC for 20 years taking care of
CREC's computer networks, including
maintaining and troubleshooting the
wiring, and supporting the network
He said that like a forestry
department, he works to put out fires in
the network. Each day brings new
challenges and new problems to solve.

see ISD, page 4




Meet ISD .. .from page 3
Gary has an Associate of Science
degree in electronic technology from PCC,
and first came to CREC to implement a new
telephone system. In the years he has been
at CREC, Gary said the center has gone
through a huge technological growth, and
considering where the network is now,
CREC is on the forefront of technology with
its premium equipment. He was
instrumental in the conversion to CREC's
new IP-based telephone system in 2001.
After working at CREC for 20 years,
Gary said he has learned a lot from co-
workers and enjoys the challenges his job
brings. He has been honored as CREC
Employee of the Year twice in his career,
most recently in 2002.
Gary met his wife, Diana, at CREC,
when she was working for the FDOC. They
have been married for 16 years and have
two sons, David, 9, and Jonathan, 6. He
enjoys spending time with his family and is
very involved in his church, where he is a
deacon, a member of the choir and a
Sunday School teacher in the youth
