We split the tent, which is a Walrus Arch Rival XV Tent. My wife hiked in Lowa Renegade GTX boots, and I went through 3 pairs of trail runners (New Balance 945, New Balance 845, and a pair of Montrails).
I don't have many pictures of the gear, but here I am filtering water somewhere between Killington, VT and Hanover, NH with the packs in front.
