On the idea of a bear getting “leverage” on a bear canister…
From the Wild Ideas website: “Store away from tent, but do not attempt to secure in place (this will only give leverage to bears and other animals).” I’ve seen/read this other places as well. I believe this is more theory than empirical fact, but it makes sense to me.
Imagine you don’t have opposable thumbs but you do have a strong jaw and you want to open a jar. You could clamp your mouth around the lid, but you couldn’t twist or pry it off because you need to hold the jar itself at the same time. You could try to hold the jar down with your arm, but it is more likely to roll than to stay clamped in one spot. If you bolted the jar down then you would leverage and would have a better chance of getting the lid off. That’s the idea with not tightly “wedging” a bear canister in between rocks, it could give the bear something to pull on the lid against. But definitely a good idea to “corral” the bear can so it can’t be rolled away easily, such as in between some rocks or fallen trees or in a cluster of bushes.
In reality, my experiences have been similar to what others are describing — I’ve seen bears in the Sierra but my bear canister has never been so much as tipped over. In particular, the Sierra bears for the most part have learned that tackling a bear can is a waste of energy so they don’t even try any more. Which is the whole point. Any bear that hasn’t learned that lesson yet can have at mine all night if it wants, let it play slobber hockey until it gives up. But I don’t want that happening too close to my camp because a frustrated bear that thinks it has yummy snacks in its possession can be aggressive and unpredictable.
Even though I don’t use it very much, usually one big trip a year out West, it still made economic and weight-tradeoff sense for me to buy the Bearikade. It’s 10 oz lighter than a BV500, saves even more weight compared to a Garcia, and keeping that off my back is well worth it.
And while Bearikades are very expensive, they also have very high resale value, so owning one then selling it after a few good uses actually could be a very economical way to go.
