I caught 2 big snappers while turtle trapping as a teen on the same outing (20 & 26 lbs) but didn't have a gunny sack like an idiot. I was fighting the first one nonstop as it tried to cross the back seat of my john-boat, and I kept smacking it's nose with a stick to keep it back while I rowed to the next trap. Then I caught the second one, and wondered how I would get back home fighting 2 turtles with my feet close to them while I rowed back across the lake.
Well, I chucked the second one over the seat to where the first one was and those 2 raging mad reptiles took one look at each other and locked onto each other's jaws. They never moved all the way back. LOL.
