Hey Jim,

Thanks for the reply. The heat is what is really worrying me. I have been pretty much to all of those places (except the skywalk, and I really need to do Grand Canyon again). I had thought perhaps of doing some slot canyons, but the idea of being oven baked is just not my idea of fun. :P

I guess I was wondering if there are any relatively close 'high altitude' places around Las Vegas which will be a bit cooler. Steve Kossack was telling me that last week it was 94 degrees. Yuck...and July is going to be a lot hotter. :P

James
