DON'T SPRAY AND PRAY!!
Equally important to having your bear spray with you in the backcountry is having it accessible, knowing how and when to use it, and understanding its limitations. Factors affecting the effectiveness of a bear deterrent can include range, wind, spray time, and many others. Understanding these factors and practicing with your bear spray before any actual encounter situation is essential to the successful deterrent of a bear using a bear spray. And if all else fails, just know who in your group is the slowest runner and as long as you outrun them... ;) And of course, educate yourselves! I recommend Backcountry Bear Basics by Dave Smith.
