The RiverBassin Trail was set up pretty good. There was a meeting the night before where everyone was given an official measuring board and a "secret" item that must be visible in the picture. Ours was a sticker. A valid fish had to be photographed on the ruler, with that sticker, as well as our boat number visible in the pic. Check in was at 1600 and at that point you turned your SIM card in to the tournament director. They downloaded your photos and returned your card.
