Unused Bear Spray - How to recycle / reuse?
First ever visit to Yellowstone... we got the double pack Bear spray from Costco... I really hope we don't get to use it. How do I responsibly get rid of it at the end of the trip? I don't want to waste and throw away stuff that costs $45. Is there someway I can pass it on to someone else and help them out? Would appreciate any tips...
