I should have mentioned this sooner (I was reminded about it in a message I received yesterday). . . .
The Ottawa Citizen newspaper in Canada sent a reporter to travel through Ohio this summer, following a route through cities and towns believed to have been part of the Underground Railroad. The reporter, Chris Lackner (along with photographer Malcolm Taylor), began his journey in northern Kentucky in June, and arrived in Sandusky on August 21. You can read more about this reporter's journey here; he also wrote a daily blog on the trip, which is here.
