Another Oregonian here...
You may already know this, but you are truly in the land of the mini (or VSE -- Very Small Equine) in CDE competitions. If you haven't already checked it out, Happs in Ethel, Washington is at the forefront of NW CDE. Maureen Harkcom, the director, is incredibly helpful and very supportive of VSEs.
Happs has its BIG event coming up in June, but also has a couple of schooling shows in May and another in September. Their website, www.happs-inc.com
, is loaded with tons of information about their events, including the dressage tests used for any given event.
Another site to check out is cde4vse. If nothing else, you should get in touch with the site's founder, Leia Gibson, who has won many northwest CDEs with her 32 inch mini, Kody. www.minihorsecde.com
is another great resource with everything the beginner needs to know.
There are several northwest trainers specializing in CDE, including Dorothy Whiteman and Terri Jones as well as many others.
Your stallion is gorgeous, and while I'm hardly the expert, he appears to be getting his hindquarters under himself, much unlike many horses trained just for the breed show ring.
Good luck on your quest, and if you're ever interested in beach driving, we have a Yahoo group for our gathering in Long Beach, Washington, in September. We hope to add other trail drives, but have yet to get that well organized...
