We just got back from a wonderful 10 days in the Southwest. This was our biking, hiking, and camping trip that we were in training for. We had to fly into Las Vegas, and since we had never been, we planned to stay two nights. Las Vegas is hot, and in August it's HOT. It was 107 both days. We made the mistake the first day of going out while the sun was still up. The cooling station (other than our pool) was the best thing we ran into. To do Vegas right, you have to wait till the sun goes down.
