That’d be difficult for most people. But that’s what I just did. Granted, I was in big cities with good public transport systems, first traveling on business in NYC, SF, and DC; then when I returned home to Chicago, I put my car in the shop for a transmission overhaul. “Three or four days” they promised me – but it took two weeks! Anyway, for a month I’ve been walking and on public transport.
Thank God it’s summer. I often take the train or bus downtown, then walk 1/2 mile – 1 mile to my ultimate destination. It’s amazing how differently you see the world when walking; I noticed things I’d missed before. On many days, I’ve ended up walking 4-5 miles even though I wasn’t intentionally trying to get exercise. And I lost a couple of lbs, even though I’m no longer trying to lose weight.
In DC, I even got to use their bikeshare program.
The real question is, do you need to drive as much as you do now?
