I would build it if I could, but it has to be a really great private track w/ lot of elevation changes, hairpins, stitch backs, and definitely a long straight or 2....after a while though I could see you getting bored of doing it over and over, thats why you have to make it really really interesting track, good thing about it though if you build it you could run it either way clockwise or counterclockwise to keep you intrigued but best of all its all yours and at your disposal at any given time....let me know when its built so I could go test it out w/ you
