I would only point out that willingness to drive vast cross-country distances (mostly on unrestricted highways mind you) to access really dark skies is largely an aspect of the mid-western mentality and to a lesser degree those in the far west.
I actually think of it more as a phenomenon of the Far West than the Midwest -- and for good reason. It takes forever to get anywhere in the West!
Only a vanishingly small segment of hobbyists would ever be willing to make a 7-8 hour trip EVEN ONCE A YEAR to gain a Bortle class 0-1 view.
Actually, the Great North Woods are only about a 4-hour drive from Boston, which is thinkable for a weekend. And the central Adirondacks are about 6 hours from New York.
But if I'm going to make a longer trip specifically for observing, I'm much more likely to fly to the West, where dark sites are ubiquitous and, to misquote the famous song, "the skies are not cloudy all night." I'm vastly likelier to find clear, transparent skies in the great Southwest than in Maine.
