A quick question about carrying food............. Do veteran PCT hikers carry food in a nylon stuff sack, an ursack, or some other means? Also, how do you get around the need for a bear canister in the Sierras and Yosemite?. Finally, do you tend to sleep with your food, hide it in the rocks or does everyone actually sling it over a tree every night? Thanks for the insights. -- Mike Maurer
