How did I not know about this? You're right @OldGuyot about it being little-known.
Just did a quick scan of the site and based upon the general route, it would appear that one would have lodging options available most, if not all nights. It's about 1-1/2 - 2 hours drive south of me, so I'm not super familiar with the areas it encompasses. @KathyIngle are you familiar at all with Maryland's Eastern Shore? Or Annapolis?
The Northern route through Illinois runs about 20 minutes from where I live.
@Rob6 - I am asking myself the same question. Guess I know what trail I'll be hitting sections of soon enough
