We full-timed for about 10 years, part-timed for about 10, in that time we wintered in Arizona and Texas. We considered Florida but found the costs were much higher than either of the other two. A lot higher.
We settled on a place in the RGV. Today a cool front, the locals call it a COLD front came thru, dropping the morning temps down to 69 with 34% humidity. Folks in sweat shirts this morning......
Remember, the closer to the water, the more bugs and when the wind is blowing, the cooler/colder it will be, if coming from off shore. Georgia, S Carolina are not far enough south for me.
Poke around here for more info on the RGV.
