In-line Skating 40:00 
Have determined that it was my pump at fault after all. Needed to get another so skated in rather than wimp out with Metro once more. Got slightly overconfident and ended up laying my left hip into the pavement avoiding hitting the side of a car full tilt. A tiny bit of road rash and probably a bruise - I don't think it will be at all serious vis-a-vis this weekend.
In-line Skating 18:00 
From work to Nadim and Peggy's for mapping committee meeting on slightly wet pavement. Just barely got to bike shop en route in time for them to take pity on me and let me buy a pump.
