When I took off from the San Diego area and headed to Tucson to visit with a friend and member of SRP I stopped in a place called 'Datewood' AZ at 11 am for fuel for the bike and some water for me. They had a bulb style thermometer that was in the shade and it was 106 degs F.
I have no idea how frigging hot it was when I landed at my friend's place in Tucson at 3:30 pm but it was HOT!!
