Dave and I hike Bondcliff, Mts. Bond, West Bond and South Twin. 14 hours.Dave and I hike Bondcliff, Mts. Bond, West Bond and South Twin. 14 hours. 25.9mi (almost a marathon!), 4900'. Lincoln Woods to Wilderness Trail to Bondcliff Trail to Twinway to Twin Brook Trail to Franconia Brook Trail to Lincoln Woods Trail. Beautiful day, but finishing at 11:30pm was perhaps suboptimal. And South Twin didn't even help, since it doesn't even get done independently; we could have turned back instead of doing the loop.
