You can find members near you by going to "community", then "members list", then click on "search members" (this is hard to find, it's in the heavy blue bar about 1/3 of the way down the page), then click on "advanced search" at the bottom of the pop-up window.
Now fill in the town name or any of the other data and the search will be filtered by what you type in.
I filled in "Seattle," at least 100 posts, and last post "since 2012-01-01". The results were:
3Ms75Argosy...1975 Argosy 26
man7sell......1964 19' Globetrotter
nmbosa........1959 26' Overlander
If you use the same filters for Washington state, you get 34 names. I know there are some active Streamers out there who don't post much, or at all, so you will miss a few, but if you don't use effective filters the list will be full of names who have joined, but who really aren't enthusiasts.
I see that LACI80
is also in Tonasket, joined in June 2012, but has zero posts so far.
