I was reading another news account about this incident and noticed the following:

"Gottsegen told Denver's KMGH-TV that the first person to go around a corner yelled that there was a bear and then started running backward. Then Gottsegen said he looked behind him and saw the bear so he started running down the hill. He said the bear tackled him on the way down."

This stood out because earlier today I read this:

"Smith believes one of the primary reasons bear spray works is that it gives users a reason to stand their ground. Running is the worst response to an aggressive bear, he said, "but it's hard not to. Just picture the meanest dog in your neighborhood and multiply his size by ten-it's very hard to keep your feet from running, but bear spray gives you an option. When you stop and plant your feet, that makes them stop.""
