Got her stuck in a sand bar.
Hate to sound patronizing, but I once went wheeling by myself and spent the next three days trying to get my ZJ out of the middle of a swamp. After it got moving, I got stuck again 15 feet later. But since I followed these steps, the second time I got stuck it only took 10 minutes to get out.
Step one, stop spinning your wheels and digging yourself into a hole. Once you're stuck up to the axle, $#!t get's serious. Try reverse. Still stuck?
Step two, lower tire pressure to 10 psi. Before driving on sand, I would do this beforehand. In a desperate situation on non beadlock wheels I've gone down to 6psi.... scary times. See if you can get out. If not, read on...
Step three, get your jack out and get it ready.
Step four, find stuff to put under your jack to keep it from sinking into the sand.
Step five find more stuff to shove under your tires.
Step six, jack up the axles and shove stuff under all your wheels. Not just the one's that are spinning. Once you think you have enough, add more. Ideally, you have the jeep back on level ground.
Or spend $250 on a locker and skip the whole scenario.
