Shooting my AR at the south site about 10 years ago. I was back about 200 yards, and the place was deserted. I had a spotter placed about 50 yards forward and about 45° off to one side.

I had what I thought was a clear view of the entire field up to the target. I had fired about 3 shots and had the slack up on the trigger for number 4. The shot was milliseconds from breaking. My spotter started shouting "CEASE FIRE" in a somewhat panicked tone of voice. I relaxed my trigger finger just as a father and son motored through my line of fire on a small motorcycle. Had my spotter not warned me, I'd have hit one of them almost for certain.

It turns out there is a very shallow depression in that field that is just capable of hiding a rider. We walked through it, but didn't notice it when we were hanging the target. It was completely invisible from the shooting position.

That situation scared me so badly I didn't fire another shot for over a year. I had nightmares about killing one of those people for months after.

Every time I think about that day, I thank God I didn't kill anyone.

As you can imagine, I'm even more careful now, and I was almost paranoid careful before that incident. You just can't be too cautious.
