On the way back I stopped to pick up two clean cut teen boys. Alpine people were always picking up kids walking home. They wanted to be let off in AF canyon to meet some friends. They said to let them off at the highway, but I said, I will just run you into the camp ground. When I pulled in, there was what looked like 3 runaway kids. A fat kid with no shirt, about 15 smoking a sig came out and yelled at the two kids and threatened to shoot me with the 357. I slowly backed out as he was aiming the gun at me. Luckily he didn't shoot. He was only three or four feet away. They were gone when the AF police got there.
