I was in LV in 2012, in August. Night time low was 110! LOL However, until you experience "dry heat" you will never understand it. I will take that 110* heat over a humid 80* any day. I sweat, like a well run race horse, so within minutes of being in the 80* humid heat, I am drenched, but in Vegas, I was comfortable. My son and I walked from Circus Circus to whateverthehelltheplaceis that has the pirate show. Wasn't bad at all. I had stopped at a town in Utah just off the Interstate on the way back and was amazed to see all the greenery, it was nestled in a small valley and I said, Man I could live here!
