This Troop 111 document is full of sound advice but omits some key points about planning trips in bear country.
First, Scouters should check the regulations and guidelines of the wilderness area they are visiting.
For California, SierraWildBear will give you the recommendations/requirements for all the wilderness areas and national parks.
For many regions, the bears are learning how to get food that is hanging from trees and, much to the chagrin of those of us who want to go light, hard sided bear cannisters are required.
Second, if you really want to manage/reduce the risk of a bear encounter, go to places where there are fewer bears or the bears are less accustomed to acquiring thier food from humans. (Little Yosemite Valley comes to mind as a camping spot to avoid.)
