I agree with Susan.

When I lived up north in a very small rural community, we would often find bears right in our backyard and in the forest and fields close by. Most times the bear would turn tail and run once they caught our scent.

Other times the bear would come in closer for a closer look and sniff then not pay attention to us at all and continue about it's business.

The odd occasion, a bear would be aggressive and start swinging it's head and with ears back, advance towards us. These are the bears to really watch for...they feel threatened and you need to be very careful to stay calm and give the bear as much room as possible...this also applies for any other types of bear encounter such as I wrote about above.
