An older pic of descending LotS after an overnight trail-maintenance session (also rode/pushed up Lots as OtR was snowed in at that point) Sleeping bag is on bar, tarp/sleeping pad on right fork leg, bivvy sack on left. Gear stored vertically on the legs has a much lower moment of inertia and will impact steering less than across the bars. It also has a lower CoG. With this setup, I was almost able to keep pace with the rest of the crew who were handicapped by having their trail tools strapped to their packs.
