SUMMARY: Link to Bay Team page.
I've just filled in a lot of accumulated wisdom about the USDAA Cynosports World Championships in Scottsdale on this Bay Team page; includes some info about renting RVs, what to expect at the site, background info, and maps (from last year's program that most of us never saw).
There's also a lot of stuff specific to traveling from the Bay Area.
If you are a Bay Team member, you can log in and add to the wiki page. If you're not a Bay Team member--we'd like to allow nonBTers to edit it, and I think I can figure out how to do it. Just email me if you want to try (webmaster (at) bayteam (dot) org; mention that I said to do this in case someone other than me gets the message).
