Stephane and I did a two day trackday at Buttonwillow. It was between 95 and 100 degrees most of the day, but going for two days was an interesting experience. We drove up Friday night and got to Buttonwillow at around 1am in the morning. The hotel screwed up our reservation but made good by giving us two rooms for the night. The first day was tough. It took a while to get used the heat and I had never been on the track before.
