Hi Eric,

Great to see some love for coastal Maine, where I have no local knowledge
Do you think there may be a MapRoulette challenge in there perhaps? Or a
tasking manager job so we can distribute work?
I'd be in favor of replacing county boundaries with something more recent
seeing how bad the quality is. Would require conflation and fixing
relations at the edges of the work area, I guess, but may be worth it.
