Grade school I walked (I would have thought at least a couple of miles, but 0.97 miles by mapquest; what a disappointment).
Junior high school: 1.4 miles on my blue (color of my eyes) 3-speed Schwinn or when a new junior high was built, a 1.1 mile walk 1.1.
High school: ashamed to say that bicycles weren't cool, so I drove a 52 chevy until a totalled it. serves me right. Lost a front tooth as a continual reminder of the error of my ways.
College: lived on campus; subway everywhere else
Mission: walked, bus
Grad school: bicycle, classic Raleigh until I left it in the back yard and it was stolen
First jobs: carpool, then bus (every day across the Golden Gate Bridge; inspiring)
Post grad school: back to bike, sometimes subway, but bike was cheaper
Then several years wandering in the wilderness, until I returned to run/bus or bike/bus about a dozen years ago.
