I voted "threatened, but not shot at", but that was before I remembered an incident that happened when I was 12.
At a friend's birthday party (camp-out sleepover in his yard), we decided to go for a walk sometime around midnight. Idiots that we were, we thought it'd be fun to do some "doorbell ditching". At midnight. Well, we rang the bell on the wrong house. When we heard the guy yelling, my friends all booked down the road. I'm not a fast runner, so I hid in the brush on the other side of the road. Fellow came to the door, fired a .22 blindly out into the night. I heard the impact on a shed behind me. I don't think he saw me, or he probably would have kept shooting. That's the only time I've ever been "shot at", if you can call it that.
Around the same age, I also had a run-in with an old man when trespassing on his property. My friend and I were walking through the woods, and cutting through this guy's property. At the time, we were walking along a road that passed a small pond. There was a cardboard sign nailed to a tree, handwritten, that said "Fishing here may cause lead poisoning". I didn't know what the hell that meant at the time. Well, as we're walking along, this old man appears on the road, yelling at us. He points to the sign, and says, "You see that sign?! That's the lead IN YOUR ASS, BOY!" (Oh, I get it...) He went on to say that he was going to go back to his house and get his gun, load it with snake-shot, come back and shoot us both. More than a little taken aback, I apologized to the guy, and promised to leave right away. He was still pissed, but he let us go... lead-free.
Aside from those nostalgic memories of youthful stupidity, the only time I've been "threatened" with a gun was by a pair of Sheriff's Deputies... who happened upon me while target shooting on BLM land. This, by the way, was an earlier incident than the one I recently made a thread about. Nothing came of this incident, except a warning not to shoot in that particular spot anymore, and another warning that due to the expired tags on my car's license plates, if they ever saw a car in the county that even looked like mine, they'd pull it over (I like to think of this as a variation of the old "Get out of town before sundown" line...). Since the various state DMVs I had to deal with seemed incapable of acknowledging my ownership of that particular car, I had to go buy a new one.
