The OP should now look at alternatives.
1. Get the phone number of 2 or 3 taxi cab services -- You never know when you might need a taxi now that you are car free. I have used taxi service twice this year alone so this is important.
2. Get the Phone number of Avis/Hertz or any rental car service --- This can be quite expensive but a bargain compared to owning a vehicle. I've rented a car twice in the last five years. Actually, this is more expensive then calling a taxi but worth it if you have multiple stops.
3. ZipCar --- I'm actually looking into this service since they are near me. I like the fact they offer the first service for practically free! I'm going to give this a try just to see how it works!
4. Bus/Rail options --- I have bus and rail schedules saved on my computer and it helps me time them and avoid waiting that dreaded half hour or more for the bus. I also printed a mini day schedule listing when the bus arrives at my corner so I don't even need to look at a full schedule.
5. Folding bikes - When used with transit, gives you maximum flexibility for transportation.
