George, I regret I haven't been able to check this thread recently and respond to your kind offer. I know there are other "pizza" types in the area - there was a beautiful layout at the Just Trains Open House in Concord last year. I went there this year (today actually) and it wasn't there. I'd be interested in sharing ideas, stuff, photos, etc. with like-minded folks in the Bay Area. Maybe someday, if there's enough interest, we could have our own "meet."
There are quite a few train clubs in the greater Bay Area. The two stores I frequent are Just Trains in Concord and a place in San Jose (can't remember the name right now). Not many around but Just Trains has always met my needs.
