As someone who moved somewhere with public transit, it's the best. I can walk to most stuff I need within my neighborhood within 20 minutes to an hour (ironically the hour is to the auto repair shop), or I can bike places, or take a bus or train to places that are outside that area. It means that I stop drinking on nights out because I don't want to feel like shit in the morning instead of because I need to sober up to get home (and it means I can go home when I feel like it)
