After a stop at a lovely hotel on our way through Ohio, we went looking for a gas station. Google maps happened to pop up that there was a house nearby that was a stop on the Underground Railroad. Of course, we went looking for it.
While it was a fairly short stop, it was neat. The house and its ground were not open to the public but there was an historical marker out front that we stopped to read.
These types of interesting finds are what make trips like this so fascinating and fun. We could never plan for this type of an experience and so stumbling upon these signs makes for a fun addition to road trips. (Note to self: stop more often on our normal routes!)
