Have no clue what it is. I know that area like the back of my hand....fishing it 3-6 days a week from July up through May. It was not there earlier in the day or later in the day. As a matter of fact it was not there on the return pass...or several other passes. I will many times single pole troll to give myself a break from casting. Whatever it was moved in a matter of minutes......I went over same track exactly...saved track on iPilot.
