My trip to Atlanta for the holidays has turned into a longer stay because home (Moab) is freezing right now. Looking to spend ~month climbing here, ideally at a single location (budget concerns). I've got a van and my double rack but left my 70m in Utah. Is T-Wall doable long-term, or should I focus on bouldering? Are there any free options for self-contained camping vehicles around HP40?

Chattanooga, you have the crack and great bouldering in a warmish climate all in one town. I dont understand what the question is.

the inversion in Moab can be a bitch sometimes eh?

Without a rope or partner, is T-Wall worth going to? Easy to meet up with parties in need of another ropegun? Also, are any free camping options around HP40?

check into rocktown. they might have a time limit on how long you can stay. camping is free, but you need a georgia rec pass (GORP). lost wall is right down the road if you find a rope.

Chattanooga would be the place to hang. I have heard that the DNR have recently posted new signs along the road at TWall preventing camping in most of the 'overflow' areas. It is always packed there on the weekends when it's cold. But, there are cliff lines everywhere and more boulders than you could ever climb around Chattanooga!
