Is there any way to get around the country for free?

I am a native North Carolinian who moved to Minnesota this past year.While I love the North Star State, and I detest the attitudes espoused by many in the Old North State, my girlfriend, who I have not seen in over two years, lives there.

I do not have a car, as my family is poor and we have never had an extra car. I also made the glorious mistake of going to college and majoring in something I loved, but it is only applicable in the cities (particularly New York and D.C., as it is Euro Studies.) Ergo, in the glorious stuck-in-the-40s Mississippi River town I am in with its 8000 people and no jobs that people have not occupied for less than 15 years (and the local factory having fired me because I cannot stand for more than 6 hours,) my job prospects are limited unless the local telemarketer picks me up, and even then I am afraid of calling people usually. This is why I do not have a car or the means to pay the 500 dollars a trip to the nearest train station (which is still 83 minutes away by car.)

Because I only have ~100 dollars to live on for this trip, I already have to forgo sleeping. But I need to know if there is ANY way for me to get around the country for free, even if it's as close as Minneapolis.

(Yes, I considered indentured servitude, but it is illegal here in America, and was phased out of the British Empire a long time ago as well, oh, and removing a person's rights for any amount of time will lead to enslavement and lowered living conditions.)

Also, please do not just say "get a job" because I am trying, or go off on me for being a freeloader because again, I am more in an "I cannot do anything about this" scenario than an "I am being lazy and don't want to do anything about this" scenario.
