Some years ago was in the Southern California desert for the weekend with the class C and buggy.
Got up one morning and went outside, notice a sidewinder's track in the sand leading under the motorhome. I carefully checked around the RV looking for the exit path,,, none could be found.
Not being completely stupid I wasn't about to crawl under there to look for it so left later that day, still no exit path in the sand.
Never did find that thing, guess it fell off on the way back to San Diego, either that or I have a petrified snake somewhere in the bowels of the old class C.
