too cold for this old gal :) we live near MB and go alot to the state parks in the area for summer time and when we do a CG like MB Travel Park (for the indoor pool in winter/lower cost) we freeze for sure. But some might be ok with that. Not 'warm enough' for me as a 'wintering place' at all. My sights in on GA or FL for over winter.
We were just at Apache cg and the older couple, our neighbors, are doing Oct to March and they are from upstate NY...they say they are fine with the tougher winter beach weather. whatever floats your boat kinda thing.
