I think the Silverball Museum is just down the road at Asbury Park? I wonder if it is still open; I visited it about 10 years ago and spent almost an entire day. I think it was $20 for free play and there we tons of machines, including many older ones. The owner seemed to have a particular affinity for Evel Knievel because I recall there were about 10 EKs in various states of repair being worked on, including at least one em version. Good time! I would go back if I am ever in the region again (assuming it is still open).
