Here is a thought. Why couldn't we still use Gathland State Park for alternative Fall MAHHA but cap the number of participants to make the park rangers happy?
I've always wanted to visit the Finger Lakes (ever since I read Theodore Dreiser's An American Tragedy), but I'd like a centrally located place that maximizes the amount of people that could attend. Finger Lakes is no better than West Virginia, in that it is on the absolute fringes of the definition of "Mid-Atlantic States."
Just a thought.
