I'm headed out to Yellowstone country to spend more than a month backpacking and car camping. I've been several times before, but not for any length of time in about 10 years. Clearly the number of bear attacks/deaths has become more of a concern during the past 3 or 4 years for rather inexplicable reasons. I've never bothered with bear spray before, but now it seems like something I should have with me both backpacking and day hiking and car camping, mostly solo and most of the car camping will be at the more remote sites like Slough Creek, my favorite.
In looking at bear spray on line, all of the pepper sprays listed as "Bear Spray" seem to have a minimum of 7oz. of ingredient plus the metal and plastic container, for a total weight of 15 or so oz., I'd guess. That's pretty heavy to me. I also noticed that several companies make smaller "Personal Protection" sprays that seem to have exactly the same ingredients, but spray a lesser distance. So those of you who regularly carry bear spray: What is the lightest bear spray that will be functional? Thanks.
PS: I have camped, dayhiked, and backpacked in Yellowstone before, both for more than a month at a time and also solo, and also backpacked and car camped/dayhiked several times in Denali. I am not looking for general guidance on bear avoidance and danger/attack minimization. Thanks.
