A friend of ours just returned from an extensive fishing trip in Alaska where he saw many bears. (They like to fish too, lol!). He told us about an incident that very much impressed upon him the absolute importance of never running or moving quickly in the presence of a bear. Seems that a bear appeared on the opposite bank of the stream where a group of men were fishing. They moved off to a safe distance like sensible people but one of the men accidentally left a newspaper behind. A few minutes later the wind took the newspaper. The bear's reaction to just the quick movement of the newspaper was INSTANT and he immediately charged after it at full (and very impressive) speed. Our friend said it was a lesson he'll never forget - whatever you do, DO NOT RUN!
