Fort Martin is located along CR 53 (Fort Martin Road), 4 miles past the junction with WV 100, just past the Fort Martin (green state placed) sign. There is a nearby Methodist Church, but I'm not sure its the one mentioned in the maker. I would have loved to stop and find out, but the rain was threatening a downpour and I left the rain gear at home.
Please take note! CR 53 may seem like a nice twisty road with reasonable pavement to play on, but be warned, heavy coal trucks frequently cross the yellow in the corners. Also, a street sweeper (no I'm not kidding) makes passes on this road spreading the gravel out. Definitely, take the speed down a notch and keep the eyes up.
