About two months ago it was me and my uncle fishing the kentucky side of the ohio river and we had a three lines get tangled. I wasnt sure if it was one of mine lines or not so i just left my line in the water and let him untangle his mess. I was using a circle hook with a bait castor that didn't have a clicker so i just left my reel on free spool when all of sudden my line start shooting out going upstream. When i set the spool the pole got hammered and then my drag started to come out then it all went slack and i sadly reeled in to see what appeared to be the line snapped. Thats when i looked down to my right to see my hook and leader siting on the deck where my uncle had just cut it out of the tangle. This realy confused me cause something had hit my loop of line left in the river and took off. I never got what ever it was to stop and if it was going down stream i would have said it was just a log but it was going upstream. Ive heard of sturgen and big spoonbills coming out of the ohio. Could one of them snaged on my line? Any thoughts or similar experiences?
