i have driven through some deep dry quick sand pits in southern utah in my wrangler, and never aired down. i was prepared to if required.
in all my years only stuck twice, once i used a hi-lift jack, with a 2'x2' foot board to jack up the front and back of the jeep and push it out. toward the side, of a pit (this was my mistake, i actually came to a stop so I could photograph paul bunyan's potty

), second time was this july, and a guy driving a black h3, pulled me out.
