If you are with someone both of you can run. You don’t have to outrun the bear, only your companion. Just kidding.
You cut a hole in the ice and put peas around it. When the bear comes to take a pea, you kick him in the ice hole. /sorry
This is valid information and it is good of you to share.
I also would like to share some advice to people who will be traveling in bear country.
The best advice is to wear little bells on parts of your clothing that will ring whenever you are moving. It is also good practice to carry a can of strong pepper spray.
It is important to know what type of bear might be in your surroundings. The best way to determine the type of bear you may encounter is by examining the bear's scat, or droppings.
Black bear scat will usually consist of fur, berries, and fish bones. Brown bear scat will usually smell like pepper spray and contain little bells.
