Years ago we were out on a riding trip and one of my buddies blew out his knee on his way over the handlebars. After we took him to the ER, we packed him up and his wife said she could drive the trailer home. I called her that night and she said she didn't know how to back it into their driveway to park it behind the house, so I went over after work the next day to help out.
They had one of those Power Caster electric dollies, so I threaded the needle between their fence and house and got the trailer to the back yard. When it was time to stop, I realized that I hadn't thought things all the way through and had no way to stop the thing. (I learned later that there was a connection to the trailer brakes that I hadn't been briefed on.)
Somehow I managed to use my Fred Flintstone brakes and drag my heels to stop their trailer just in time. Scared the snot out of me.
I think of that freewheeling trailer whenever I unhitch.
