The location information is from notes by Larry Zinn. The barn is along the old section of US Rt. 50 which was abandoned when the US Rt. 30/OH Rt. 32 (James A Rhodes Highway) was constructed. In photo 3 (Google satellite view) the barn is clearly recognizable. Compare the location of the silo in the two photos with the location of the silo in the satellite view. Also note that, when looking at the Mail Pouch end of the barn there is a shed extension projecting out from the end of the barn. This shed extension is also visible in photo 3. Because of the treeline along old US Rt. 50 and the fact that that section is no longer travelled it is not surprsing that the Mail Pouch sign has not been noticed.
Where to find it
