Ride a bike.
Why do people in the US love their cars? Because they give them freedom. Not having a car means getting the freedom of keeping your money, but giving up the freedom of just jumping in the car and going somewhere. The bike gives some of that freedom back. Bikes are cheap, they get you some exercise while moving you from place to place and you can maintain them for less than $100.00 a year. Plus, they are fun to ride. Reclaim that kid feeling and get on a bike.
