OT: I lived in Bullhead City, AZ for many years. It has the distinction of being one of the hottest places in AZ. There is a place in Death Valley, CA called Hell. I remember a headline in the Arizona Republic that said, "Bullhead City Hotter than Hell!" It was 128 degrees. (Patio thermometers peg out at 120 degrees.) But your right, the low humidity makes it more bearable. A popular T-shirt for tourists showed two skeletons sweating in the sun and said, "But it's a dry heat!"
My hubby, who was a contractor, would leave for work at 4 a.m. and it would be 104. We retired to cool Oregon.
