Twenty four people trampling through the wood would make enough noise to alert any bears in the area. So the choice to confront, was the bear's choice. This may be a start of a problem bear since that bear choose to stay and bushwhack the tourist group. Most bears will simply move on. So unless there were dinner (bear kill) nearby or some daycare for bear cubs these tourists didn't see....this bear may have to be put down.  Just food for thought....
