Let me start this post by stating that I am an idiot.
I left home this morning for my 7.5 mile commute with no frame pump and about 3 miles in, got a flat. Fortunately, I was close to a bus route, so I hoofed it over there and made it to work in a reasonably timely fashion. Thing is, now I'm 7 miles from home with a patch kit, a flat rear tire, no pump, and a presta spare. There's a gas station down the road, but I don't know of any way to inflate my presta spare at that gas station.
Does anyone have a method for inflating a presta tube using a gas station air pump and pocket knife that would save me from calling my mom for a ride and feeling like a total ******bag? I would be forever in your debt.
