A short walk through the woods off the Greenville-Brownville road brings you to one of the more haunting historical sites in Maine: the broken remains of a B-52 Stratofortress, scattered across the snow-grass forest floor more or less where they fell in 1963. The crew names are inscribed on a small memorial; the wreckage itself is untouched — tail section, engines, fragments of fuselage.
About 25 minutes' drive from Greenville Junction; the last few miles are on a rough gravel road. Free; open year-round.
