Assume he did not carry a canister or ask for an exemption. With the possible exception of the bridge in Yosemite he did not camp or sleep in any area where canisters are required: Just below Mather, Mono Creek below Silver, and some bridge - not clear which one - around the 22 mile mark at Tuolumne. He may have been on thin ice sleeping with food in his pack but by then of course, he had about the amount of food left you might carry in your pockets, so who knows how he had it arranged for the last 2-hour nap.
Anyone want to bust him for that?
