5. Variety

Variation on a theme: last wednesday, had my backpack ready by 11pm, 26 pounds worth, then up at 5, on bike by 5:15, on bus 5:30. In nicer weather, with a lighter pack, I would have ridden longer, to a bus stop 6 miles away instead of 2. Arrive at 6:15, up the hill to the hospital by 6:30 for a 24-hr call. Next morning, bike a couple of miles to transit center, then bus to airport, leaving my bike securely locked. Sunday carpool to airport, light rail to downtown, bus to home. I'll run to bus Monday, pick up my bike, back at last on routine.
