Devon is the "city" that will come closest to appearing on most maps. In more specific terms of location, go a few miles below Matewan and Delorme on the inaccessible section of track heading to Iaeger and you'll find Devon/Ought One.
Speaking of the Pokey run, any ideas as to when the 765 might be doing the ferry move? Sure would be cool to catch it at Kenova again, but going over the C&O tracks instead of going down them.
