Where the jungle’s dense it is impassable, but there are a fair number of places where the trees are spaced a few meters apart and the undergrowth is only knee-high, and light shines through. By moving from one such place to another they make slow progress in the general direction indicated by Randy’s GPS. Jackie Woo and John Nguyen have disappeared, and appear to be moving parallel to them but much more quietly. The jungle is a nice place to visit, but you wouldn’t want to live, or even stop moving, there. Just as the beggars in Intramuros see you as a bipedal automatic teller machine, the insects here see you as a big slab of animated but not very well defended food. The ability to move, far from being a deterrent, serves as an unforgeable guarantee of freshness. The canopy’s tentpoles are huge trees—"Octomelis sumatrana," says Enoch Root—with narrow buttress roots splayed out explosively in every direction, as thin and sharp as machetes sunk into the earth. Some of them are almost completely obscured by colossal philodendrons winding up their trunks.
