OK, I'm reading through Zinn's maintenance books and there's a reference to using condensed milk in inner tube to plug holes when they develop. It ressurected an old memory. LONG, LONG ago a biker came through My Home Town USA and struck up some chat with my dad. In the course of talk he [the biker] mentioned his tubes were filled with milk!! I thought it odd at the time but haven't thought of it for years.
Any one else ever hear about this or actually do it?
