It used to be VERY popular in eastern Co.
My Granpa told me they had several trucks just for it, including a half track.
I know of some guys that used to put big block chevys in old cars, chop the roof off, put in a roll cage and some mud tires and haul ASS!
One guy drives , the other stands up and shotgunns em'
I also know of guys that died or were maimed doing it.
Iv'e hit enough crapp I din't see in wheat feilds just driving from set to set , I would never try it.
Pretty stupid.
And un-sportsmanlike. /ubbthreads/images/graemlins/frown.gif
