in an early thread about relocating to DC Plenz, you suggested a zipcar membership...I am looking at this option and am doing some reading about the service...can you provide actual user experience? pros, cons, advice on useage? I am not ready to invest in a car payment and philly has the service...I can use septa for getting to work, going out for a night on the town, but there are times I would like to have a car at my disposal....
thanks in advice for any help...
