I did the ERC class here in Phoenix out at Luke AFB, in August 2007, Still Air, had to be 112-115 in the shade, I have no idea what it was out on the Concrete. I was suffering from heat exhaustion, nearly passed out on the bike pulled out of the exercises, had to rest and rehydrate. Idling the bike around the course at 15-20 most of the day, Heat rising off up off the rear cylinder and into my face was unbearable, not my Idea of fun. Gear was all completely soaked, helmet was slimy, my mess jacket was wet. the bike was overheated and pinging pretty bad until I got back out on the road to get airflow over the cylinders, and cool everything off.
I really feel your pain.
