|Never, never carry bicycles on the back of a trailer!
The bike didn't separate completely from the trailer because I always use a safety cable to keep it attached to the trailer in case of rack failure, it just got dragged along until I finally got to a spot wide enough to get off the road. The first time a bicycle rack failed I was on I-85 sandwiched between 18 wheelers. This is the second time it has happened to me, believe me, it won't happen again.
I told Jack how the bike was damaged. “Oh, I get these that fall off bike racks all the time,” he replied. “Yours is not too bad.”
Nevertheless, he wanted the Lady Raleigh we placed temptingly in front of him. The Lady Raleigh had the traditional skinny road tires that my wife wanted to get rid of. She couldn't go off road in any sense of the word, and wanted a bicycle more suited to dirt or gravel roads. My old mountain-bike damaged the front wheel and tire, and luckily, suffered no other damage when it too, crashed to the highway.
