Riding beats walking any tiime ;-)

Long stretches of my commute includes a bike trail where public transportation doesn't go. Save for two or three spots, cars can't go there, either. So if you have a flat or a mechanical problem you can't fix, you're in for a long walk back to one of these places if indeed you can call your Sweetie for a ride home.

I carry spare tubes, patch kit, frame pump, CO2 inflator, a couple of CO2 cartridges, a Park MTB-3 multi-tool... in fact, my rack trunk would probably make Yehuda Moon proud ;-)

But I can usually fix what's messed up, and limp on home, or help a fellow rider do so.
