Here's a little summary of the transportation for my trip. Who knows, maybe one of my readers would like to do something similar. If you're ever in the states and want to get around cheaply there's only a few options.
Boston, MA -Providence, RI --> Peter Pan Bus, 45 mins- $8.00
Providence, RI- Washington, DC --> By car with a friend. 8 hours- about $22 in tolls, plus gas (I paid for the tolls)
Washington, DC - Pittsburgh, PA --> Megabus, 6 hours- $7.00
Pittsburgh, PA - Cleveland, OH --> Megabus, 2.5 hours- $17.00
Cleveland, OH - New York City, NY --> Greyhound, 9 hours- $59.00
New York City, NY- Boston, MA --> Megabus, 4 hours- $13.00
