Lesson 1. False Casts Ruin ¿¿Fishing
I was able to slide right into a run without spooking trout. They weren't bothered by a big ¿¿bubble-blowing blob, so long as I moved slowly. But as soon as photographer Tim Romano moved the boom-operated underwater camera overhead, even ever so subtly, the fish scattered in panic. At one point, a shadow passed above and I saw fish slink away toward the rocks. When I surfaced to ask what had happened, they told me a blue heron had flown over the run.

More significantly, I watched from be¿¿low as my friend Bruce Mardick made several false casts over the fish. As he whipped the line back and forth, the fish went ballistic and hid against the bank. After allowing them to recover, he started limiting false casts, even using roll casts, and the trout seemed undisturbed. The point: You get one, maybe two, false casts before the fish are onto you. Try to direct these at an angle behind the fish; only your final cast should target the run.
