Several years ago we were camping at a new to us campground. There were several loops. On the first day I realized we ran out one of the propane tanks so I removed the tank and put it in the bed of my pick-up and drove to town to fill it up. Upon our return I backed into the space and pulled the tank cover only to see both propane tanks there. My brain couldn't accept this as I had the refilled tank in my hand. My wife was walking to the door and called out and asked why I had so much junk piled up near the door. At that moment it dawned on us that we were at someone else's identical TT. Fortunately they weren't home and we had a good laugh about it. Thanks for bringing back that memory!
