Camping in Yellowstone? Rangers ask that you fend off grizzly bears (should you ever see one) with chili spray instead of firearms, according to the Associated Press. Grizzly bears have killed a reported five people in Yellowstone National Park in the last 100 years, yet the potential threat is enough to keep visitors armed and ready. As of February 2010, firearms are legally allowed inside most national parks, leaving rangers worried that impulse will trump logic if visitors stumble upon a grizzly. Therefore, they kindly request that campers arm themselves with liquid spray instead of bullets. In the meantime, we ask that you familiarize yourself with preventative methods so that you and your family won't have to worry at all.
