We worked Yellowstone/Canyon Village in 2011. That was the year with 2 fatalities 3 miles from us within a month or so apart.
Another day, a guy came in to buy replacement can as he had just used it on a bear.
Buy spray before you get in the Park. It will be more expensive inside Park.
This is our 3rd year at Grand Teton N.P. At Colter Bay. Talk about daily sightings of bears!!
Bear bells are a waste of $$. They are just not loud enough!! Just listen when you pass someone who wears them, how inaudible they really are!
If you don't want to spend the $ on bear spray, at least talk, sing, call out loudly as you are walking ANYWHERE there is a tree.
Bear spray works on angry Moose, angry elk, angry buffalo too...
