Red Circles

I saw where T_om mentioned running over an alligator it reminded me about the time my little brother-n-law and I were night fishing a creek on Lake Livingston in Texas. We were in a 14 ft jon boat and had hung a lantern in a dead tree and backed off as to be able to cast under it. While shining a light around we saw two round red circles and wondered what it was. I motored over to the tree and we removed the lantern then turned toward the red circles. When we got about 20 feet from them the alligator rolled and looked like it was as long as our boat. I hit the throttle and after a few seconds I realized I didn't know if I was in the channel or not. I slowed down and looked around. When I hit the throttle I had dead centered the channel. Thank God I didn't turn us over by hitting something underwater.:fish
