Have you ever been attacked by a wild animal?

A few times, yes. On one occasion, I was biking by a family of geese and I must've gotten too close to the goslings. The mother rushed me, hissed, and flapped her wings, but did not make contact. So calling this an attack is perhaps questionable, as it merely intended to deter me.

More noticeable was an incident back at Boy Scout camp. We were practicing our water rescue tests and a snapping turtle emerged between myself and the boat and chased me at least a few meters. The turtle was very slow, but I was wearing a life jacket, and thus, was also very slow. It was genuinely quite frightening.

I'm also pretty sure squirrels used to throw stuff at my ankles while running near my school and other runners reported the same. But that's unconfirmed.
