Great stories!
I think I was about 35 when I bought my 1st pin, Hang Glider, which I still have today. I was bitten pretty hard at the time and quickly added Top Score, plus 2 projects. I stayed there for a couple years and then sold 3 machines to pursue other interests. Two years ago, I decided to build a game room and have since jumped in with both feet and bought 8 more machines, with more to come.
I find it funny that when you tell people you collect pinball machines, their reactions are usually peculiar. But when they visit and play them, they start asking where they can get one.
