It wasn't an issue last July / August. Some days were better than others, but it never felt miserable. The vent fan doesn't help a ton, but the window air conditioner seemed to make a big difference. I usually started it a 1/2 hour before climbing.toad857 wrote:
chriss: i would imagine that 4 or 5 people up there climbing in the summer would get hot as balls, even with the fan... any problems with that?
As a note though, it was only me climbing and I live in Wisconsin. It doesn't get quite as warm and humid as Kentucky.
