LOL mrdeath, some of that mud has been wet for a while so it sorta smells like it...
My best freind, Jack lives off of Kolb and I10 and builds mud truck engines,( You probly seen it sitten out there along the frontage road just east of kolb) but there is a spot out there I think past the prison wear he tests his engines... It's pretty large from the vids. probly some good mud out there and alot of open space to play...
Here's a vid of him testing one of his engines (this vid is from a camera phone so quality is poor, but you can see the area I'm talking about).
Here is his truck. He's builing another killer engine for it.... He also is building a wrangler from the ground up.
Here is a vid of him racing with the old engine:
Anyhow, back on topic....There are places to play.
I'll call him and see where exactly this place is.
