Was camping at a State Park in Oregon and across the road was a pull thru site. Watched a new 5er pull in and start setting up. He must have just picked up the trailer and stopped by the lumber yard because he started pulling out 2X6 lumber and saw horses and a skil saw. Started cutting up the lumber for ramps right there in the park. Then backed up and pulled forward several times till he got it level. Sad thing was that it was an unused handicap site and he could only stay in that one night. Had to move the next day and start all over again! Practice, practice, practice.
