Humidity buh-looooows. I've dealt with 100+ temps in twentynine palms CA and iraq, sometimes over 110, but I could never deal with the humidity in north carolina
Dry heat is different, even 80 with high humidity seems to suck the energy right out of you. It especially sucks because I can't drive with the windows down in that atmosphere. My mileage instantly went from 24 to under 22 (computer est) yesterday when I drove back from work
I tell you one thing though, I still love the auto climate control better than normal controls
