I and my family have had several instances where guns were needed!
1) My dad, back in the early 70's was walking in the woods in the fall and ran into (almost literally) a black bear. The bear snarled and growled. My dad only had a wimpy (ok, lets not get all bent outta shape over that joke) 45, 1911 but he took it out and let off one warning shot and the bear decided he didn't like that racket, and took off hell bent for election.
2) On a camping trip when I was about 12, we were at a state park in northern MN and were sleeping in our camping trailer when a bunch of bikers pulled in crankin on their throttles at about 2 or 3 AM. My dad, back in the day, was a real hard-azz and took no sh*t from anyone... he got out of the camper with a lever action 30-30 and cranked off a round through the trees..... to catch their attention I guess. The decided to ride on and find another place. By the time his round went off, my uncle was also out of their camper with his Model 29 S&W ready to go. ha ha
3) My brother and I were small game hunting when a skunk came at my brother on a dead run... never saw that before! He must have been rabid.... anyway, 2 rounds from a 12 guage at WAY TO CLOSE range sent him on to the happy stinking grounds.
Let's put it this way... in the woods/nature, there is no reason not to be prepared. Sure, we hopefully/probably will never need it, but isn't it smarter to have it and not need it, than the other way around?
The way this world is now, it's nuts to go in the great outdoors without a gun.... no i'm not paranoid... why should I be, I have the gun! ha ha
