Professur said:Came damn close to that this morning. I was unzipping one of the bunks on the trailer, and the zipper disintegrated into a handful of teeth. While I was busting a nut trying to figure out how to sew a new 3' zipper into already fragile canvas (and where the hell do you even get a 3' zipper? I was thinking about sacraficing a sleeping bag) Mum comes to the rescue with that miracle of modern science : Velcro.
Velcro is FANTASTIC! It paid for most of my Uni education
