Thought I would start up a thread on my visit to the National Pinball Museum. I didn't go from Michigan to Virginia to go there (business trip), but when I heard about it, I had to check it out. It's located in Georgetown, MD. Right now they have March Madness going on and it is $10 to get in and you get $2.00 on the game card (not sure if this is everyday). The normal price is $13.50 to get in. They operate from Thursday - Sunday, but they may be going to Friday - Sunday soon from what the employee told me. I did meet the owner, David, and he was a nice guy and very knowledgeable about the history of pinball and how it is a part of American history.
The Pay-to-Play room is nice and has a good selection of about 25 games. They also have a few games at $1 in a special section about Stan Fukuoka (Big Bang Bar, Kingpin, and Breakshot). They even have one of the original run of the Big Bang Bar games. I plan to upload some more pictures later, but I just got back to Michigan and am very tired.
Enjoy! https://picasaweb.google.com/judremy/NationalPinballMuseum?feat=directlink
