(great thread Pete)
I have only been collecting for 3 years.
Never even saw a pinball machine anywhere between the ages of 7 yrs and 38 yrs, then started collecting apx 3 yrs ago. (I am 41 yrs old).
I always find it bizzare that i never even saw a pinball machine anywhere for over 31 years, which is amazing, but shows how rare pinball machines really are. (and I used to be in Real Estate and look at thousands of property's ever year as well !)
Only 3 years.
