I've got a couple.
1987 near Cooks Creek on the Satsop River in early December. Air temp around 30 or so. There is a guy fishing in blue jeans waded out to his sack. His dog is running around on the bank. About an hour into fishing, I go to make a cast with my 8wt. On the forward stroke, my rod just stops. I'm thinking I must have hooked a bush or something behind me. I turn around and there is the dog with a size 4 pink bunny leech hooked through his ear. I try to get the dog to come to me so I can remove the fly. It growls, shows its teeth and takes off running. I give chase while yelling at the guy to stop his dog. The dog is just abusing my new Teeny 200 fly line as it runs around through the bushes. The guy finally gets the dog in his grips. He is half blue from wet wading but doesn't seem to be bothered by it. I offer him my pliers to cut the hook. Instead, he wraps my 10 lb Maxima leader around his hand several times, grabs the dog by the scruff of the neck and rips the fly out of the dogs ear. The ear is now split open and blood is spewing everywhere. I love dogs and greatly dislike folks who mistreat them. I asked him why he did that to the dog. I really felt bad for the dog. The guy didn't say anything or seem to care that the dog was injured. He just went back, waded out and started fishing.
If I had had a cell phone back then, I would have turned the ******* in for animal cruelty.

1990
Shilshole ramp. Guy launches his new boat, around 24 feet or so.
Wife is standing on the dock holding the bow rope. Part of the bow rope is lying in the water. As the husband pulls out the trailer, the trailer fender catches the part of the bow rope that is in the water. The bow rope is ripped from the wifes hands and snags on the trailer. Has the guy is driving up the ramp, the boat comes flying up out of the water behind the trailer and onto the ramp a good 15 feet from the edge of the water. If anyone ever wonders what that white line is on the ramp at Shilshole, now you know. To funny and you should have seen when they had to get it back on the trailer.
