I took 2 pins (pinbot and BoP) to a show 6 years ago and I have been on the board that ran Pin-a-Go-Go and now runs the Golden State Pinball Festival for the last 4. Getting involved with the show is a great way to give back to the community and to meet other pinheads. Clean and wax your machine before you take it so it's well protected and enjoy watching people enjoy it.
