Now this might be a tad difficult in Seattle since a quick check of the internet shows the closest gun dealers are in Bellingham. This is a nice town and people there definitely know what guns are for. No doubt locals can direct folks to the right places.
There are also supposed to be "gun shows" in rural Washington State every weekend too.
Look...this is obviously a sensitive subject to me, and I think this Gibson thing has run its course here. This will haunt him for the rest of his life. It's been interesting to see what people here really think and I've been shocked at some of the totally anti-semetic statement some have made. But hey, everyone is entitled to their opinion. You're not really Jewish, are you???? :)
