A friend of mine actually found this little jem, and here's a quote of what he had to say about it:
"Travelling on the cheap
I know that my fellow Twin Citians from time to time have the need, or at least the desire, to go to Chicago. Now there's a new company that can get you there for as little as $1. That's not a typo - as little as one US dollar from Minneapolis to Chicago. The catch, of course, is that you're on a bus. And the shorter the notice when you book your ticket, the more you'll end up paying. On the other hand, if you're planning ahead, this can save you a lot of money. And unlike Amtrak or Greyhound, you don't have to deal with a lot of stops along the way. They also have routes back and forth from Chicago to Milwaukee, Cincinnati, Indianapolis, Cleveland, St. Louis, and Detroit."
Which really just says it all.
