While I would not give up the four seasons, it is nice to spend a few days in warmer temperatures.
Last year we went out to Phoenix for a muzzleloading rifle shoot. This year we are spending the first three weeks of January in Florida.
We dry camp till we get south far enough to add water.
When we get back to Indiana, we will re-winterize and head for the State Park to do some dry camping and snowshoeing.
We have spent some nice nights in Georgia which is not all that much of a trip from TN.
It is in the 50s in FL today which is fine but in two day it will be back to the 70s which is even better.
Try a mid-winter weekend a bit farther south. If you do not like it you can always wait for spring.
