Grab an insurance policy, charge $10 admission and sell em hotdogs and sink hole memorabilia.......
I'd make it $20.00.
I think you guys are thinking too small. I say build a couple ramps, line up some of those adrenalin craving extreme sports junkies, and jump it for bragging rights.....all on pay-per-view.
"Soar Over The Sink".....live. $49.95
