I'd say Shumi is spot on. If you could spend 10K/yr on karting, you'd have the best equipment, always fresh tires and motors. When I ran those at Willow, I could hit 105 MPH on the back straight (slightly downhill) when the winds were right. Fastest guy in the club could do almost 140. If that don't stand up your stud, I don't know what will.

Karting has been proven to be safer than skiing.

Oh, and I meant to say that 10K will cover everything including travel and meals unless you take it to the extreme.
