Another vote for Pin-A-Go-Go here. It's a pinball-only show, in a small town just outside Sacramento, with a very family oriented feel and atmosphere. The whole show is very laid back and folksy. Food on-site, fun tournaments, lots of hanging out and talking shop with fellow pinheads, Borygard is there to fix your pin's boards, cool vendors, amazing raffles(including TWO pinball machines), swap meet on Saturday morning…. I could go on and on. It's just a great time.
