It's definitely good to check out the Florida section of Regionals on the main site (small print, towards the top right of the homepage), but many people join theme camps with folks from all over. If you can't contribute towards a local build before the Burn, contributing money and work hours on the playa are pretty standard. So don't let it stop you from looking at any camp in the 2012 Theme Camps forum, or in the Theme Camps section of the main site, especially in a month or two after the ticket situation starts evolving a little more, and people can plan. If you see a camp that resonates with you, send them a little letter about yourself, what you have to offer, and why a specific camp appeals to you.
You can also camp "alone"--you will have neighbors immediately!
