Read a story about a photographer in Saigon who was standing curbside with his camera bag over his shoulder. Along comes two guys on a motorcycle and off goes his camera bag.
The next few days he does the same thing, but stands next to a street lamp of some sort. Along comes a motorcycle with two guys and off goes his camera bag. About 12-15 feet of paracord reels out until the line goes taught between the light post and the camera bag and pulls the second guy off the motorcycle. The first guy loses control and dumps the bike.
No, I was not there, just a story I read.
