The company I worked for used to set up Electrical Engineering seminars to keep it's people informed of the latest developments in electronics. For several years , a fellow eng. and I used to draw the same time slots for our refresher courses. He was from Wyoming ,and said he and his wife frequently took there three young children , with them on long walks through the back country. At the time , there were a couple griz. attacks , one fatal , on elk hunters in the same area where they lived. He said , his wife , and he , and kids walked in a line , w/mom first , three kids next , and dad in the rear. Mom carried a 3" mag. pump shotgun , w/ 2 , 00 buck in the chamber and magazine , and a rifled slug last , for follow up , and dad the same in the rear. He said they would never challenge a bear , but felt between them , they could defend themselves. Don't think I personally want to go at it , w/any grizzer.
