This started out as the Mid-Eastern Orangeburg Way, but then I extended it all the way up to the 12th Street Extension in Cayce, SC. 125 miles of fun, with a lot of dirt included. The red & blue lines are tracks
that meet in Rowesville, SC, and the Southern end of the red track meets Marsh Tiger's fabulous HO-CAT route (gray loop at the bottom of this image).
EDIT: I improved the route from near North to near Swansea a lot on 05/31/12 - more & better dirt, more rural & scenic - and attached the new file, so re-download it if you got it before then!
