Well I was out riding the trails in Battell Woods today when I happened to slam my rear wheel into a rock unusually hard.  Not 15 minutes later I knocked another rock awkwardly with my rear tire, finding a hissing sound singing out.  No big deal, I had a spare tube and was borrowing a pump as mine was in storage.  I pop my rear wheel off, pry the tire off, and pull out the popped tube.  Get out the new tube, grab the pump, and WHOOPS, the pump doesn’t fit.  Now I’ve got a totally flat rear tire and a long walk home.  Luckily I was graced with the most beautiful weather and was able to grocery shop on the way back.  Finishing out my ride bombing down Chipman Hill woulda been pretty sweet though.  Next time…
