I have been to Glacier and Yellowstone numerous times. This is a good reminder for where ever you are at in Grizzly Country to be prepared. I will be replacing my expired bear spray as well as arming my wife for our summer hiking plans. I always carried a 9mm because of capacity but going to switch to my 10mm this year. Condolences to family of the deceased and hope the two attacked in Yellowstone will be ok.
