Durham and Epping are also right in the seacoast area, which already has Seabrook. The area where they are truly needed are farther north. The planned Conway location would be ideal, as it would make trips up to Lancaster, Colebrook, and environs a lot less challenging. Last time I went up north I had to stop at a PlugShare home charger just to make it back to Lincoln, Not to mention that charging in Lincoln requires you to go way out of your way if you're heading back to the seacoast.
Agreed. I've written Tesla about upping the priority on the Conway supercharger. It will make Boston -> Whites a much more stress-free trip. This Rochester supercharger is going to be wicked helpful, but wont make it quite as seamless as the eventual Conway supercharger will!
