Ick. I don't 'do' hot. Perhaps its too many generations of family living in or around New England. Not to mention, a mail truck is the last place you want to be in +100F weather. Oven. On. Wheels. [/pittmode]
I used to drive an aluminum stepvan, similar to our LLV's and FFV's, only bigger.
I was delivering one hot, Tuesday in Charleston, WV, with nothing to cool me than the breeze thru the doors, and the ice water in my cooler. While driving to my next delivery, I noticed my shoes felt sticky, like I had stepped in some gum or something equally nasty.
It was neither. The soles of my shoes were melting on the floorboard!.
Back in 1977, at the height of the "Coming Ice Age" talk, we stayed snowbound the entire month of January, bitterly cold temps, winds, etc. Spent the entire month thawing water pipes and cutting firewood.
August rolls around, and we set 21 record high temps for the month.
