hmm.... this probably sounds kinda silly, buuuuut....
why not buy a plot of land... and pave your own parking lot/course
i'm sure somewhere around here (particularly not miami...) there's some good locations out there, within most of our reach, where property value isn't all that high yet...can be a decent sized plot of land,
i'm not saying, "hey guys, let's get everyone in this community to donate $10 to raise up money for a track!' either, this idea doesn't neccesarily have to be a community effort either (at least, not the comunity as a whole anyway) it could be... an idea that reaches a couple of ppl who have (or can find) the means to make it possible... those ppl could be enticed by the idea, and see it as investment.
i don't know where you'd get the funds tho.. most of us are either going to college, or doing something else... but i guess you can try to find the right person who feels they have something to gain from it...
anyway don't hate, i'm just tossing random ideas out there...
kinda like a crazy horse stripping in front of an old notebook on the last day of school....
