Railbiking. Anyone built one?
I heard an interview today with author William Least Heat-Moon. In his latest book, he meets a man who has built an outrigger bicycle he calls a "Railcycle", which he uses to ride on disused railroad tracks all over the world.
Curious, I did some searching, and found a number of places on the web where people are talking about this, but they all seem outdated.
Has anyone else heard of this practice? Do you know of anyone currently making and riding such contraptions? Do you have one of your own?
