If you're going to protect yourself from a *really* dangerous animal, carry mosquito repellent & camp with mosquito netting.
Statistical comparisons of unrelated risks can be useful in allocating resources. For example, if you have $100 to spend a tire pressure monitor for the wife's car is going reduce her overall risks a lot more than getting her some bear spray.
PS. Anyone know what makes a *doe* (not a buck) become aggressive? Twice in the last year I've seen a deer (doe) aggressively chase off a dog in my front yard. I didn't know they did that and would hate to trigger one getting the mail.
In both cases the dog charged the doe while barking. The doe stood in place then charged the dog when the dog got within 10 feet or so. I think the dogs are still running...
