We got stuck in a sand Quarry.We followed the arrow pointing to the campground. I guess it was pointing in the wrong direction. We had a 31 foot class A motor home towing a Jeep wrangler. We followed the road till it came to a dead end.  Well we had to do a uee and it was a sand quarry. Both the motor home and the jeep were stuck. We unhitched the Jeep and I dug that out with a small garden shovel,  then the motor home. All the while the workers are standing their laughing. We were quite embarrassed. Well anyway make sure you carry a good size shovel
