Love it, BSR! I'm in South Florida and though temps don't get much above 95 in the summer here, the humidity is sweltering. You walk out of the air-conditioned house and it's like smacking into a wall. The air is so heavy it slows your breathing. We have the same tools and outside car work rules here, too. I use a garden hose, after I've let all the hot sun-heated water out of it, of course.
The worst part for me is that I sweat profusely from my head when I even think about work, and then the sweat gets into my eyes and drips down my face, making it extremely uncomfortable to do even the most simple chore. I now take a terrycloth washcloth and tie it around my head like a bandana - it helps, but I still have to carry another in my pocket to wipe my face from time to time. I think I would welcome a dry heat a little better because of this, but I'd prefer less heat to begin with!
Ah, well, in a few months I'll be complaining about the cold in Maine. It's all relative! ;-)
