Yep, I think a problem was TREC was competing with Dirt Riot and was established. With what looks to be the demise of TREC, Dirt Riot might have a chance. But I don't know how big of a turn out they would get.
We will likely have to travel to race. Kinda like if you build a hard core crawler or bouncer and want to use it to its fullest potential, you'll have to travel. The local parks have made it much better, but it's hard to compete with the natural terrain of areas like Rausch Creek, Harlan, Windrock, Canada, and all the cool areas West of the Mississippi.
