Las Vegas again.....

I am going to Las Vegas again !!!
I was there in August 2007 for 16 days, this time I will be going for two weeks, august 25th till September 7th.
I will be traveling with two friends, and I can't wait for August to come :o)
Last time it was soooooo warm, so I hope this time it will be a bit cooler, so we can be outside a bit more.
I would love to see some thing away from the strip, like a local marked or so, so if anyone knows of things like that, please let me know.
Saw Hoover Dam and Grand Canyon last time, so I would love to see other things this time.

I think I will get a book about what to see in Las Vegas, so I can check out what I don't want to miss this time.
