Pageland is right off US151 - the same road that Darlington is on. For you, I don't know if it'd be better to just run 9 the whole way, or if you'd want to run 74 all the way to Monroe, and hit 601S, which turns into 151.

If you're going to use Mapquest, use
2380 Peach Orchard Rd
Jefferson, SC
The track is a mile or two past that address, but Mapquest doesn't recognize their physical address for some reason.
