we had the same thing here awhile back, funny thing is after the wrecker pulled him out one weekend we saw him do the exact same thing the very next weekend.
a few weeks ago a guy does the same thing with a dodge turbo-diesel dually 4wd and he gets stuck so he revs the crap out of it and launches- when his rear wheels hit the berm at the waterline the truck went like a foot in the air, his girlfriend is like " yeah baby thats turbo power right there". I was surprised the axle didnt fall right out of that thing. couchwatching is my new favorite pastime. I used to like boatramp watchin but this is way better, and becoming easier to find-unfortunately.
