You want to add to that route and have some twisty road fun. Take 541 to the other side (west)of Coshocton, then grab 60 north all the way to Killbuck, do a little zigzag over to 520, take 520 to 514, 514 to Danville, 62 to 36, 36 to MTV. You can thank me later.
If your route is through Coshocton, take Hwy 541 west from Rte 16, following that to 586 in Martinsburg. turning right will take you into Mt. Vernon...
