Bears, even though I think they're really cool. It's gotten worse over time. I've seen a lot of videos of idiots interacting with them, getting too close, leaving food out at campsites, etc.

Plus my ever-declining faith in humanity, it means the likelihood of a bear I would encounter being made more dangerous because of other people is high.

I used to want to go to the Adirondack mountains, but after reading reviews about one of the main camp areas being overrun with black bears (due to eating human food) that's no longer on my bucket list.

Even on a fairly recent camping trip with a friend with equal knowledge about bear safety, they left a plate out with some meat grease overnight. We heard all sorts of sounds and the plate was far from the eating area in the morning. Like can you not leave a welcome present out for the apex predator, please?
