Solo hike on Marlboro Trail to Mt Monadnock, return via Smith Summit Tr., stopping at Monte Rosa, then Great Pasture Tr. back to Marlboro Tr. in Jaffrey, NH, USA. Beautiful 70-80F partly cloudy day. The Marlboro trail was much more quiet than the usual way up Mt Monadnock and I passed only one person on the Smith Summit and Great Pasture Trails, despite there being nearly 100 people on the summit!
