Hi Josh,
WA has a pretty active state club with a picnic and 2 meets per year. I would suggest tagging along to those as they are a good place to meet people. Most people I've met so far in WA are friendly to new comers, some even went out of their way to introduce themselves (which i'd never seen in other states i've lived in) at the last meet I went to. WA also has quite a few people who fly kestrels from what I've heard through the grapevine. There are also quite a few people in the seattle area.

Really the only book about kestrels in American Kestrels in Modern Falconry. It's a real quick read but good information for someone with limited knowledge.
