When I was a kid my father was a dairyman, which meant we lived on a farm with other dairymen and their famlies as housing was usually part of the compensation. One particular farm had 2 mobile homes near each other with two propane tanks. One was directly behind the other. Those tanks became horses, cars in high speed chases, runaway trains, boats, jet planes, rockets, you name it, we probably imagined it, except for a bucking bronco watermelon! Thanks for the chuckle! I bet your kids had a good laugh too!
