Moving to Boston after college?

After I graduate college, I would like to have at least 4k saved up and would like to move to Boston. I have always wanted to live there, but I really don't feel that my plan is truly practical. I am hoping to land some sot of job in a PR firm, considering that my major is PR. With the way the economy is now though, I am sure it would be difficult to do. Anyways, my questions is: is 4k enough to just start out in Boston until I find a job? Should I live on the outskirts of Boston, instead of right in the city ( It may be cheaper) Should I take my car, or commute? Or is this whole plan just a terrible idea? I really just need thoughts and ideas. My parents aren't fond of this and don't really support it, so it would be great if I could have other thoughts! Thanks! PS: people keep constantly saying, " why Boston? People are so snotty there?" I always reply that you can find snotty people anywhere....I just wanted thoughts on that as well :)
