<human>: Provide a brief overview of the text.

There are some limitations here, the big two being financial and that I'm traveling alone. 

The deal is I'm 27 and I have no friends where I am because I moved here for a PhD program two years ago and have been buried under work ever since. This summer, I need to get the fuck out for a bit. I'm from a big city but will be spending minimal time there this year because my ex is friends with all my friends there, and seeing her wouldn't be good. 

I have barely traveled before. When all's said and done I'll have about 8K to last me through the summer (that includes living and traveling; I pay $725 in rent). Where in should the U.S. should I go by myself, for either a weekend or a couple weeks? I'm thinking of doing 2 or 3 mini trips rather than one long trip. I do not have a car. 

Thanks all.
