There are some good gun shows here in Western Washington. The Washington Arms Collectors put on the shows with the most floor space and selection, even an area for the Saturday-only vendors. Of course ther are the non-firearms related tables, but I bypass those all too quickly.
A smaller show is put on by Falcon Productions, and centers in the northern reaches of Puget Sound. Fair shows, but some times you find something that just 'whispers' to you (like a Montgomery Ward Western Field No 5 .22lr pistol with original box, holster, and owner's manual for $150, later tracked it down to being made by Unique in France, manufacture date 1954).
There's smaller shows, but with the current price of gas going down (but not fast enough) I may not get to one of those for a while.
