When I first got my Tesla, I did a road trip from CT to Dayton, OH. Back then, there was no supercharging route through Pennsylvania (now there are several). I had to drive from Connecticut south to Newark, DE, north west to Hagerstown, MD, then to Somerset, PA, then really far north to Cranberry, PA, then west again. I actually had to plan to stop at an RV park in Zanesville to charge between Cranberry and Columbus (where there were only HPWC at the mall), but one week before my trip, a SC opened up at Wheeling/Triadelphia, WV which was like a godsend so I could avoid the RV park stop all together.
