Great time to come to Arizona, I am sure you will have a great time. Some fun things to do...
Friday Night -- Have dinner and drinks at AZ88
in Old Town Scottsdale. It's a very gay-friendly "mixed" crowd on Fridays with fun inexpensive food and premium bar. Great crowd, fun atmosphere, famous for their LARGE martinis.http://www.az88.com/
Then head downtown to Rebar, which has sort of become the after-dinner gay hot-spot in Phoenix...http://blissonfourth.com/
Saturday or Sunday during the day, try to do the hike up Camelback Mountain in the center of town. Great exercise, incredible views of the entire metropolitan area, and hotties everywhere you look. It's the ultimate "urban hiking" experience...http://www.phoenixasap.com/camelback-mountain.htmlhttp://www.toddshikingguide.com/Hikes/Arizona/Phoenix/Phx3.htm
Saturday Night --- BS WEST in Old Town Scottsdale is probably your best bet for a gay club (if your here on a Wednesday Night, that is their big gay college night and it's always packed). http://www.bswest.com/
