It looks like you've got a good excuse to visit Palm Springs, California. On August 13-16, 2009, there's an event that looks like it'll be a winner:
Palm Springs Salsa & Rueda Congress!
Aug 13-16, 2009
Wyndham Resort & Convention Center
I spent some time looking over the schedule and it's for sure something I'd like to go to. The schedule indicates an exciting and equal mix not only of salsa (lot's of on1) but also casino rueda. Enough said, eh?
Seriously, it looks like a lot of thought went into making the event something that beginners and intermediate dancers would not feel left out at. Here's the URL:
