have maps of dual sport routes/gravel roads in the upstate SC?[/QUOTE]
That Horsepasture Rd. area is nice, I found it several years ago on a tip from some Asheville guys, doesn't appear open in summer though. Here's a (sizable) day loop you guys could do a little west of there, I can't do a gps file at the moment but here are directions.
From 11 head N on 130 quite a way, then left on Cheohee Valley rd, right on Cherokee Lk rd, then veer right on Winding stairs rd. Right on 107, left on Burrells Ford rd, right on 28, left on Warwoman then just down the hill (at bridge) right on Overflow Creek rd, cont. N onto Hale Ridge rd to 106 and turn right, then left on Turtle Pond rd. Right on 28, cont. straight thru Highlands (don't turn) and becomes Horse Cove rd. At fork go right on Bull Pen rd (nice picnic spot at the iron bridge) then right on 107, left on Oscar Wiginton then right back onto 130. Seven of those roads are gravel, some more maintained than others, and easily doable on a KLR, Wee, GS, etc., no water crossings but plenty of good scenery. Maybe one of yall can map it, get the mileage and estimate the time it takes. It's probably a relatively full day from Greenville counting lunch and pit stops.
