Most of those tracks are over 1 hour away. One has closed that was 45 min. One is 33 min. Since I drive 2 hours to Louisville one hr 45 min isn't bad. Was wondering if there was enough interest to open a venue.
Greenville, SC is a neat town. When I lived in Flowery Branch, GA, we could make the drive in two hours flat, so got up that way on many occassions. The downtown area, with the river, falls and park in the center is particularly entertaining. Sorry, I don't know of any racing in the immediate area, but you'd only be a couple of hours plus a bit to get to Sling Shot Speedway and any of the Lake Lanier group venues in the Atlanta area. The racing doesn't get any better than that!
