Don't have a car? Well, I don't. Although I know it helps me maintain a smaller footprint on this Earth, it makes it incredibly inconvenient for me now that I don't live in the city. Having no car doesn't mean you're stranded though. There are lots of options! (Especially if you live in a public transportation-friendly city!) Here is what I have available to me in Asheville:
-City Bus (Not the best in Asheville; needs more routes and more frequent routes.)
-Greyhound Bus (...For when I need to go to another city, although it can be a bit on the sketchy side sometimes.)
-Bicycle (Yay for bicycles; unfortunately, I really can't ride one.)
-Renting a Car (...For when you are going on that road trip!)
There are many more options then these, of course, for others, but one option I recently found was the Zip Car. Zip Car is technically rental cars but there's a twist to these. Zip Car is actually a "car sharing" company. Zip Car's mission is to make it where people use cars less often and, therefore, so that less cars will be bought.
