I've been a WAC member for 20 some odd years, I've had tables at the Puyallup and also gone to just browse. It is one of the largest shows in the PNW.
One thing not noted in this thread is the fact that WAC is also politically active and has saved the collective butts of All of WA shooters/ firearms owners more than a few times.
So while you might think $35.00 is too much for a years membership, or the entry fee is too much, remember the WAC is on your side and fighting the anti gunners in Olympia on your behalf.
