<font color="blue"> We where just in Western N.C. visiting my ailing grandmother this weekend....</font>
Not a bad second choice, after Florida. We own a cabin near West Jefferson, in the NE corner of the state, about 30 miles NE of Boone. We don't get up there as much as we used to, but at one time we thought about spending the summers up there and the winters in Florida. As for jobs, you might be surprised. Maybe not many structural engineers, but that kind of knowledge translates to many things. West Jefferson, for example, is the home of the 1st or 2nd largest ambulance builder in the nation, for example.
There's still gotta be something wrong with your corner of FLorida, however -- maybe our county's control is more effective or something, but we haven't been bothered by mosquitos for years -- just occasionally -- nothing like when we lived up North in Massachusetts. And, the heat here never seems to get as hot as the heat up there.
There are some neat rural areas to the Southwest of Jacksonville -- maybe you should be looking to get some expansion room with a little longer commute.
