Visit sourceEvery summer morning on western tailwaters, millions of Trico mayflies mate, die, and fall to the water with their wings spread like tiny crucifixes. The trout line up and eat them with metronomic rhythm, completely ignoring anything that is not a perfect size #20-24 spent spinner drifting without a hint of drag. This is either the most technical, rewarding dry fly fishing on earth or a punishment designed by someone who hates anglers. Possibly both.
