Rear tire went flat a mile from the station this morning. Patched it by a street light. I didn't find the cause, ... might have been a pinch flat
Maybe. Could have been a sliver of glass or wire which went through the tire but didn't stay. Or maybe all the air spontaneously bored through the potential well of the tube in a quantum-mechanical manner and escaped. Or maybe you should slow down. Heisenberg tells us that if you are going too fast you never really know where the air is.
Whatever. I missed the 5:13 express, caught the 5:30 local instead.
Which prompts me to think: Good grief, you must get up at 3AM. And your morning commute must be in the dark; is your evening commute in the dark too? So what kind of lights are you running? (Yeah, I know, you may have posted that in the recent lighting thread but I don't recall specifics.)
