1) Pinball machine. Buy the pin, perhaps for a premium price. And then play play play play.
( I restored my 1st pin 2.5 years ago and have been playing it. A lot. Have not spent another dime on it. Just play. And keep clean.)
2) Hunting: gun(s), annual license, ammo, vehicle transportation. Lodging fees. etc.
3) Fishing. It is not as cheap as you think and can get quite pricey.
4) Power motor boating. Described as a hole in the water you throw money into.
5 ) Radio Controlled Airplanes. I heard this gets expensive.
What other money eating hobbies can you think of that makes pinball look like a very good entertainment value for the dollar?
Stay home. Play pins. Save Gas. etc.
I think pinball has a bright future.
