I've had a chance to talk to some Oberlin College people in the last few months, and I understand that the town is very aware of being on the ACA route, and very happy for it.
The ACA Underground Railroad route through Oberlin, doesn't use the bike route I described. It commemorates a famous abolitionist incident, called the Oberlin-Welliington rescue, by taking the highway that the rescue route followed: http://en.wikipedia.org/wiki/Oberlin-Wellington_Rescue
After Oberlin, it goes around Cleveland, passing through Medina, Ohio. There was a famous abolitionist church in Medina, and nearby Kent, Ohio, was the home of John Brown. The route highlights a lot of sites where incidents occurred, where opponents of slavery preached, and so forth.
When I was a student at Oberlin, a group of students re-enacted the underground railroad on foot. My recollection is that they actually arranged to sleep in some homes and buildings that were used to hide slaves.
