Joel,
I didn't know that you were working for Textron. I worked for them at the Cushman facility in Lincoln, NE when I was in college. I mainly worked on the turf trucks. They closed that facility and moved it to Augusta, GA. I knew some guys that took the move opportunity, but many decided to stay (some work with me now). It sounds like you have a lot of upside opportunity by the move. Yes, it will be more hot and humid in the summer, but I wouldn't consider it that cold in the winter. Moving away from Ronin would definitely be a pain, but you could run that like an east-coast office. Living closer to Charlie would definitely be fun though...
Good luck with any of your choices. Be happy that you have such great options to choose from.
Rick
