I had an incident on the Missouri river once, I would like to warn you about. I was fishing down stream from a trotline on the bank. I dont eat the fish from the Missouri at this location due to contaminates, but apparently this older fellow did, and while I was there he had come down, mainly I think to see if I was taking fish off his line. We sat and chatted for a little while, he checked his bait, and I asked him how often he ran it, since it had a lot of activity in the area and he told me during the day about every 4 hours. We talked about how he had done, ect. I explained to him that I was just fishing for the fun of it, I had plenty of fish in the freezer and had a couple of hours to kill. He left. Here is where the problem started. I caught 2 blues, one weighing about 20 lbs and a smaller one. I decided the older fellow was pretty hard up, and needed the fish, so I found some wire, that would hold the fish (since I didnt want to sacrifice one of my stringers) and put them on it. I saw this boat coming down the river, but paid no attention to it. I pull the old fellows trot line in about 4 feet (on a sand bar) and make me a loop and attach my 2 fish to it. I turned around and walk back to my gear. This boat pulled in at the line. The were apparently Wildlife officials of some sort. They asked me if that was my trotline, and I told them no, it was the older fellows and he looked like he could use the fish, and I was putting my fish on there, for him. It was not tagged, so they were trying to accuse me of running a illegal line. I finally cleared it up, when I asked them, trotlines are made to take fish off, not put them on. If it were mine, I would be taking those blues up to the truck. Finally they let me go and told me if I saw the older fellow to tell him to tag his line. I told them I would. I am pretty sure they could have given me a couple of tickets, not sure for what though. While you are out there, be aware of your surrondings, and doing someone a good deed, is not always the best thing.
