I haven't seen one here, but I'm in Central Maine. Maine's overall a low-income, high-tax state, so don't expect to see many. The money's on the milder coast, but with Portland to Bar Harbor being 157 miles one way taking US-1 I don't think there'll be many takers there. To add to the fun, when you combine sales and excise taxes you pay 7.4% up front and 4.75% over the next 4 years.
According to the Muskian Calendar, you won't see the Southern (Kennebunkport/South Portland) Supercharger until this winter and you won't see the Northern (Bangor) Supercharger until 2015. I think we'd get them even if our 551,601 households don't buy a single Model S, because Maine's a summer-home state and Bar Harbor is such a significant destination.
August 3rd run up Mt Washington? It's "only" 3 hours SSW from me so I'd be tempted to park by the Model S group and beg a ride up and down, but ironically we'll probably be going for lobster in Trenton and mini-golf on Mt Desert Island.
