Or not
I bought five large cans of bear spray a few years ago during a family trip to the Tetons and Yellowstone. A man had been mauled to death on a trail near the Grand Canyon of the Yellowstone a week before we visited. Couldn’t bring the stuff home with us, so we dropped it off in a Bear Spray donation box in Jackson on the way to the airport. I think the drop off was either at an outdoor store or a ranger station. Some lucky visitor got ours for free in the next few days.
TIP: If you are visiting bear country, try to find the free donation boxes where departing people drop their spray off. You might save some big bucks.
The Bears look in the free donation boxes too. ;)
