I've done the drive from Caliente to Vegas the last two summers in a row. I'm skipping the race up there this year. Last year's dirt bike race up there was brutal! I quit half way thru cause I didn't like the idea of heat stroke and was watching people just get the crap kicked out of them all day! I was just tossing water over my head about every 5-10 minutes the whole way home in the jeep.
