A bear entered the camp of the MCNP students near the beginning of the Yukon River trip and ripped open a new Cabela's tent. When the bear became aggressive and refused to be run off, Ron Pratt, director of MCNP, fearing for the students, had to shoot him. Later, in Fort Yukon, we ate black bear backstrap and ribs. Ron gave most of the bear meat to a native village, for which they were very grateful.
At an Athabaskan fish camp we stopped at, there was a "bear dog," a dog kept just to keep bears from stealing the fish.
Later, in a store in Anchorage, I saw a bear spray on sale, along with this (redundant) promo: "Stops harmful attacks." Are there any bear attacks that are NOT harmful?
