I put it out when I go into the woods using a flashlight. A mini-mag lite works fine. Use your thumb to cover the lens of the light with only a crack for the light to shine out of. Gives you plenty of light to walk without looking like a lighthouse coming through the woods.

A tip on the 35mm film cannisters. Cut a piece of clothes hanger wire and duct tape it to the canister. Bend a hook on it so you can hang it from a tree limb. Makes it a little easier.
