I went out to Vegas for a softball tournament in August a couple of years ago. We went from 97 and oppresive humidity to 113 and dry. Give me Vegas ANY day! Working outside in Florida sucks, and I've been lucky enough to deal with it one way or another for the past 6 years. I managed to scheme a month inside while at Space Mt, so that wasn't so bad.
Anyway, we had practice at like 2 PM in Vegas, and none of us were even sweating. Not sure if the dry heat didn't feel as bad as the humid or the sweat was evaporating before it hit the skin.....
