ultralight

Time permitting, I'll swing by the ranger station or outdoor store (REI, etc.) on my way to the airport and see if the employees can use anything I can't fly back with, e.g. fuel cans or bear spray. I tell them how much I've used and they know there's no guarantee with them. Most of the time they'll gladly take it, even if it's just for their own, off-the-clock use.
