Yes, hanging works if there's no bears. I've yet to see a hang defeat a bear. Seen many attempts that were defeated by bears. Bear poles and wires generally work. Once a bear got a food bag from a wire. Sleeping with your food works 100% of the time unless you leave the food near the door of the open tent. The rule should be to simply never leave your good unattended. When it's in a tree it's unattended and most any bear will get it if they come around.
