Notice how the one who is actually picking up the garbage on the trail is the jeeper, and not the enviornmentalist. The clips of the mudders trucks were old POS's that were sitting there with only one tire spinning in the mud and the Jeeps were heavily modified and doing their put-put down the trail. My XJ gets muddy all the time just on the drive back and forth to work, potholes, my driveway and the occasional dirt road, not the nice meadows full of flowers.
I enjoy camping and hikeing, but I'm looking for good parks around where I live where you can/need a 4x4 to get to a remote campsite, instead of hikeing 4 or 5 hours and arriving exhausted.
