About a dozen years ago, I tried the spot just downstream of the treatment plant, downstream and on the west side of the Glenmore overpass. Just as I parked and got out, I noticed two guys unloading their rods and about 18 beer. They appeared to have drank the other 6 on their way to the spot. I decided to stick around and watch for a while. More to make certain that they were okay. They weren't hurting anything, and I figured they were looped enough that the fish really didn't have to fear these guys.
Anyway, the one guy was busy talking to me over his shoulder as he was casting when I noticed that one of the seagulls that frequent that stretch of river was kind of flying off kilter. The guy starts yelling "Hey! I've got a Seagull!". About then, the bird falls out of the sky into the river. Buddy starts reeling the seagull in, and since I'm the only one nearby who isn't looped, I volunteer to help him with the bird, figuring he might have injured it.
As he pulls it in, I can see that all that has happened is the line has wrapped around the bird a couple of times, and the hook has simply crossed over the line, creating a very simple slip knot. The seagull was not injured, but man, was it MAD. I put one hand on the bird to hold it's wings where the line was wrapped around, and then reached down with my other hand to undo the line.
Snap! The dumb seagull chomps down on my thumb. Now I have to let go of the bird with my other hand, so that I have a hand to untie him. Both of the beer buddies are killing themselves laughing as the birds wings come free, and swat me a few time prior to it realizing it was free and flying off.
Somehow, by this time, I had lost my desire to fish at this spot. I left feeling somewhat comforted that no dumb animals were injured in the making of this adventure.
