I went to the track last night, at the las vegas motor speedway. my first run when I got 15.3 was at california speedway. las vegas speedway is 2000ft. an at 10:10pm it was still 95degrees. I was very disapointed with a 15.9@87

 

Elevation and heat really take it out on your times. But atleast everyone else had the same decrease in times too.
