That is just too cool for school! I'm sure that I couldn't keep up with the intensity for the duration of a race like that. But isn't that track something? I'm guessing it's something on the order of 40'-45' X 60'-70'
Agree. And it's indoors! So the guys in that area get to race all year round. That got me thinking: If you make such a cool course indoors like that, why not use carpet instead of dirt? Bartjuice, the guy trying to start up a track here in Grants Pass, said that most landlords won't like it if you haul in a few tons of dirt. So why do it with dirt at all then if it's indoors?
I've seen some cool track layouts using carpet. In fact one site that I visited recently showed how to make whoops, moguls and jumps using various materials such as pvc, carpet and plywood. Conceivably, one could make portable track components.
It's not short course, but these guys make some great on-road track components: http://www.roaddome.com/ Very nice, but a bit spendy.
Dirt is used primarily because the track surface changes with conditions and run times, with carpet it's just to specific and no fun. Remember people this is OFF-ROAD racing and the track should be just that. There is no point in racing on something that never changes it's no fun, when the track changes or "goes away" as we call it, it levels the playing field because no one person has the right setup for every situation and some do so it's more like REAL racing.
