Motionbased does not have a way to contact posters yet. There's a guy named pwoodbba, who is a rider out of Isle of Palms. He's posted some rides that include a section on the end of the Mark Clark Expressway that connects the Mt Pleasant area to Daniel Island and beyond. I am trying to figure out how he gets on an expressway legally. I'd like to do the routes he's done, but riding my bike on an expressway (even for a mile or two) seems crazy. If anyone has the answer, let me know.
Thanks to all.
