Bus and train service isn't offered in all cities. In the city I live the bus will stop here and the next stop is 70 miles away in Milwaukee.
Of course--there are other routes (but not many.
The closest train stations: Milwaukee (70 miles) or Portage (65 miles).
I think there are 2 bus companies that stop here -- with 1 stop per day to Milwaukee and 1 stop per day from Milwaukee.

I'd be interested in hearing a trip report. If someone hit me up for a ride at a gas station I think it would fluster me, but the answer would definitely be no.
