Got hung up and could not move. How did I get out?

Throw a bottle jack under the rear axle. That will raise it up high enough to be able to put some wood under the rear wheels. That should allow you to back out.

If you were my neighbor, I'd thrown a hook into your hitch, and just drug you backwards with the Jeep, the same way you got in.

if nothing else works, plug your extension cord in and call it your new home.
