Please view on black. This bobber was floating solo near the shore—apparently snagged and abandoned by its previous owner.
Lessons learned from this photo ... No. 1. Manual focus beats auto focus to pieces (at least on cheap lenses). No. 2. Tripods are necessary at 300mm (so don't forget and leave them at home). No. 3. The image in your head does not always appear on your card (deal with it).
