Given that @maddog1762 is in South Carolina, he's probably looking at the gap going north/northwest out of the Carolinas. Some strategically located SCs could be great:
- Wyethville/Fort Chiswell, VA -- on the section of interstate that is both I-77 and I-81. The Wyethville Cracker Barrel is 132 miles from Burlington NC Supercharger and 133 miles from the Charlotte Supercharger.
- Charleston WV -- at the crossroads of I-64, I-77, and I-79. 129 miles from the Wyethville site, 156 miles from Grove City OH Supercharger and 187 miles from Tridelphia.
- Morgantown WV -- intersection of I-68 and I-79. Stepping stone from Charleston to Pittsburgh.
