Hi Bev,
I don’t compete in scentwork, so I can’t help. But one resource might be the “K9noseworkPNW” yahoo group. I joined that email group, and pretty much all the posts are event announcements. It is supposed to be a forum for questions too, and I bet people would jump at the chance to give their 2 cents (however wise or not) about questions related to competition.
The group requires approval to join, but it was easy–just list some dates that you took a nosework class. Good luck with the road to competition–that sounds fun!
