I wrote last week about trying to figure out a way to put spikes into my bicycle tire in an effort to make it more snow worthy when I was a kid. As it turns out, someone else had this idea and put up a set of instructions as to how it might be done.
I was born 40 years too early or the internet came along 40 years too late. Not sure which it is yet?
Read the comments after the instructions and there is one person who gives a link to a place where you can buy studded tires for your bike. Another gives a picture of tank like treads.
