Marston Trail to N. Brother spur to Mt. Coe trail to S. Brother spur to Mt. Coe to Marston Trail, with Alex Ghitza. 11mi, 7.5hr. Mostly insides of clouds (again), except briefly at S. Brother and a bit at the end. Trail is almost completely free of boulders except at N. Brother summit. Slide on Coe treacherous in the rain, as promised in guidebook. (For a long time we were like, hey, this isn't so bad. Until the slab.) Well, it would be fun in the non-rain. "It's not just rocks around that can kill you, it's also you moving on rocks."
