Since I've been in the Sierras all my life and had no problems at all - I have seen a grand total of four black bears despite decade after decade of going into Yosemite, where the most habituated bears in the world live - I think I'm very likely doing something right. Please spare me lectures on food safety and so forth, I know how to follow the rules, which are far stricter here than in your neck of the woods.

I'm sorry you're so afraid of these creatures. Paranoia isn't going to help. All environments and all situations have a learning curve, and all risks are not equal. Statistically speaking you will have a better chance of being hurt in your own home, or on the road to the trailhead, even if you don't bother to learn anything about injury prevention. If you want some realistic ideas of the dangers in the wilderness check out some SAR statistics.

I find it interesting that you show up in a forum looking for information and reject what you're offered. You may read all the books and articles in the world - they will contradict each other, as there's a lot of outdated info and misinformation.
