I think what's worse then the heat, is piloting something that's 100lbs short of 3 tons through near upper 80's heat. I go out to my car, nice looking; beautiful. 
I come out of my car looking like death-half-baked by the middle of the day. >_O 
It's hard being a large woman, driving a car with no A/C, during the heat of late spring. ...And it's not even summer tempratures yet here in SC! 
*grumbles* It got so bad a couple of days ago, I had to pull into a gas station and just open all the windows and lay the seat back completely cause I had started to get dizzy from the heat, and I was worried I was going to get into a stinking wreck! 
At least our house has Central A/C which works wonderfully...so when I do get home, I can get into my house clothes and cool off quickly.
