Welcome to the HEAT!
Steve mentioned the Pavillions in Scottsdale, which is a bit of a drive for you but not too bad once you hop on the 101 and it is always a fairly large event wiht much more than Cobras. I am out in the east valley so anything down this way is even further for you and generally smaller thna the Pavillions.
I am sure that some of the guys on the west side will respond back with their hangouts but if not just shoot an email to mikiec at
mikec@holsum.phxcoxmail.com who is the grand poobah of the Arizona Cobras (
www.azcobras.com) and is generally in the know on what's happening.
