Goin' downstate (really, really downstate)
Thank you DJWriter:
Cycling at Southern Illinois University Carbondale, featuring road routes around Carbondale. (see Bikes on Amtrak)
Sometimes I wonder whether I'm working at the wrong university, and then I quickly banish that thought from my mind. But it's nice to know that I would theoretically be able to get around down there without imposing on my folks.
There's also the Shawnee Mountain Bike Association, if that's you're thing.
