Put it this way. It doesn't matter where you're fishing in Florida. There is always something nearby that can and will bite you given the right circumstances. I live in a nice area, private lakes etc...I've had the occasional problem with moccasins on the lake behind my house. Snake and weird critter captial if the country. It's just part of the territory with being so close to the Glades. Most of the houses west of I-95 are built on swamp land.
As far as where to live goes, pretty much anywhere will give you ample fishing opportunities. I can be at Okeechobee in an hour. Lox in about 20 minutes, or drive the boat to the Bahamas in an hour and a half after I launch it. It really all depends on what type of fishing you want to do and what kind of area you want to live in.
Personally, I wouldn't want t live anywhere else. I spent quite a while away when I was on active duty, and can't express how much more that made me love living down here. Great fishing weather all year long. Hard to ask for much more than that.
