Large dump truck coming up behind me. I spend too much time looking in my helmet mirror and go off the lip of the road (about 1-2 inches) into grass and swerve back to the left and come back onto the road. Luckily truck was a ways back and I didn't fall. Pull up to driveway to let the truck pass (crap for shoulders at this part of my 28 mile commute - mile 25.5). Road starts to feel rough/squishy - pinch flat. Get off at a safespot in the trees and replace tube only to find out either crappy little bike pump is shot or the replacement tube is shot. Ended up running/jogging the rest of the way to work. Borrowed a decent bike pump to find out I must have pinched the replacement tube while changing. Borrowing some stuff so I can go to the bike shop and get some tubes so I can make it home... Other than that, today is great out in eastern PA.
