Money is good. For those financially challenged, take a look into Karting. Not cheap but cheap by comparison and a great place to learn road racing. You don't need much of a tow vehicle, there are several tracks in the general area, entry fees and track time are cheap, and I only wish I could buy tires for those prices. Other cheap(er) forms of racing are NASA HPDE - not really racing but track day type stuff - and spec 7/pro 7. You can build a competitve spec 7 for $4K. Find the NASA web site for more info.
