Is anyone here a member of a car share? We have City Car Share and Zip Car and maybe one other one here in San Francisco, although I think I remember Zip Car buying out another car share company. I don't know how widespread car shares are, but I do know that they do exist in other cities. Have you found car share to be a good use of money? I don't own a car and can usually get around on the streetcar. Sometimes cab fare really is necessary to get things home though. The car share programs include gas and insurance and a BIGGIE in San Francisco in the form of parking spots reserved for car share drivers.
