Walking places that I can, taxi other places (I don't drive and have been living in this city for under a year), occasionally a ride from my downstairs neighbors.

Can't wait to move back home in January when my modes of transportation will change to walking, but mostly bus (the buses there, unlike where I live now are great, very timely, very easy, generally require no transfers even if you're going across town etc). That's how I lived for 2 years and it wasn't bad at all.
