I was car-free for one year when I was a freshman at college. Actually, now that I look back, that was a pretty big deal considering that we had nothing within walking distance except campus - and no public transportation where I went to school. But I did have a car on campus for my sophomore year and beyond (though I did bike to campus the one year I lived off-campus).

Now I don't see how my current lifestyle would allow me to be truly car-free. We live 10 miles from the nearest hospital, have no public transportation near our home, and 20 miles from the nearest vet and from my work (though I am getting better about commuting by bike). We try to be 'car-light' as much as possible...

Maybe someday!
