In the last five years, three people have been killed by grizzly bears in Yellowstone National Park. None of them were carrying bear spray, and according to the Park Service, only 28% of backcountry travelers utilize this most-effective defense against attacks. Now, with a new campaign called “A Bear Doesn’t Care”, the Park Service is reaching out to the public to “spread the message that bear spray is an essential tool, even for experienced Park users.” The campaign “specifically targets day-hikers and overnight campers, with an emphasis on local residents, repeat visitors, and Park employees,” says Charissa Reid, science communications specialist for the Park. The gist of the campaign: carry bear spray and know how to use it; it’s that simple. Visit go.nps.gov/bearspray for more information.
