Can't help you with bears, never been around them, boars on the other hand I've had some dealings with. For the most part the majority of big bad oar stories are hype, you run across the occasional buster bad butt, but even the majority of them make a run at you just to get past to get away. I will throw in a caveat, that both are living thinking creatures, both are ranked high on the intelligence scale so that makes both unpredictable and that is what escalates the danger potential.
