When the State first acquired the Santanoni Preserve there was great concern about overuse. When that proved not to be a problem, camping and other restrictions were lifted. I thus agree with DSettahr that Boreas Ponds are too distant from the higher peaks to likely be overused. From the ponds there could be a shorter route developed to Allen, but this would not be significantly shorter to Panther Gorge than from Elk Lake. I also think that seven miles is a long way to push a wheeled canoe carrier, and I don't think many do that for the 4.5 miles to Newcomb Lake even though that road is smoother and flatter than the road to Boreas Ponds. I believe I am correct that car top boats actually pose little danger in spreading invasives since the boat is thoroughly dry by the time it is launched.
I therefore favor the DEC's initial plan to keep the road open at least to LaBriere Flow and perhaps to the old cabin, from which it is just over 1/2 mile to Boreas Ponds. DEC has also suggested setting the wilderness boundary north of the dam at Boreas Ponds so as to be able to maintain that structure.
There is significant local opposition to these purchases - opposition that will only increase if there is the perception that access will be severely limited by terrain and distance. Governor Cuomo has promised to acquire the 50,000 acres over five years if the funding is available, but politics being what it is that funding could go elsewhere.
And while I am not going to advocate for more access than described above, I don't believe it would be the "end of the Forest Preserve as we know it" were the DEC to create an inholding to preserve the lodge at Boreas Ponds with lodge guests allowed to drive to the lodge. Such an arrangement would effectively defuse the handicapped access issue since from the lodge handicapped individuals could travel by boat much farther into the area.
