I know a couple of track owners around the Houston area and if you don't have a butt load of money and are not willing to give up all of your spare time (and this means riding bikes), faget 'bout it (as you New Yorkers say). Paying for the property, building of the track (you'll have to hire someone to do this and the people who really know how to do it, don't come cheap), equipment costs, insurance, and permits are just the beginning. Water (and lots of it); if there's not a sustainable pond on the property, you'll have to pay someone for it. Sanitation (toilets and garbage - nuff said). You can't do it alone, so you'll have labor costs. I've seen disgruntled neighbors (who moved in long AFTER the track was open) over a mile away call the county to complain about the dust and noise, causing the track to be shutdown. The parents of the first pee-wee that falls over will be suing you for negligence and endangerment even though they signed a waiver before entering the park (those documents aren't worth the paper they are written on in court). There was a fairly popular MX track in east Texas that had been open for over a dozen years shutdown by a big-shot Dallas lawyer who bought property next to it and didn't like the noise. He filed for a permanent injunction against the track in county court and won. If your track isn't kept perfectly prepped all of the time, riders (and non-riders) will be ragging on you in the forums and the local dealerships, running away business. They will complain the track is too tough, wimpy, dangerous, boring, hard packed, loamy; it's basically a no win situation. And then, there's the shifty promoters, who will make completely unreasonable demands, wanting you to join into their racing series .
