i actually made a run to the local beer dumpster last night only to go home empty handed. I never dig in too deep as I usually go in at night and don't want stick my hand into a pile of broken glass, but last night was particularly disappointing.
as for the bike shop cutting the tires, i'm assuming it's a liability issue. on the other hand, where i work everyone keeps the rideable tires that people ask to have thrown away. a few times a week we get roadies who throw out foldables that they didn't like and they make great spares, or even something to fuel a raging skidding habit. also, i've gotten a handful of nice stems from old folks who swap them out for incredibly tall ones so they can sit perfectly upright on their old road bikes. currently rocking a brand new nitto dynamic that i got for free from one of those scenarios.
still waiting to hear the story from the guy who got caught diving...
