One more thing about cans of bear spray... Make sure you do not get El Cheapo brand with the lousy trigger and trigger housing. All brands have similar contents, but make sure you get a brand that has a *reliable*, easy-to-handle trigger. I had an old can whose trigger was fumble city. I finally took it the woods and unloaded the whole thing into a field.
I think we are not supposed to bad mouth brands here, so I won't, but just pay attention to the trigger and the trigger housing when buying.
