In honor of its 25th anniversary, Penobscot Marine Museum hosts a talk by Garrett Conover. This is a chronicle of two month-long snowshoe trips from Greenville to Allagash Village, 25 years apart. The second, 2005, trip provided a fresh look at the Maine woods surrounding Moosehead Lake, the West and North Branches of the Penobscot, and the St. John River; a month long snowshoe and toboggan celebration of several conservation success stories; human powered traditional travel; and the beauty of the wilds in winter. Tickets in advance $10 nonmembers, $8 members, or at the door $15 nonmembers, $12 members. Buy tickets online  or by phone.
