The M&M represent the 4000fters that I have already done. On that side of the map I think the only ones I hadn’t completed were Galehead, Owl’s Head and Moosilauke.
After I finished my map (and each of those is half an M&M the other half being in my tummy), my friend Laurel, who has done much less peaks than me, ate the summits she had not completed yet, leaving maybe a half-dozen M&Ms in the general pemigewasset, willey range section of the map.
