Spent a few days up near Mammoth and on a local creek... I came to a wide, slow, glassy, section of the river and proceeded to watch some large and small fish grab emergers just under the surface. FINALLY the light went off and I tied on some unweighted and small bead headed nymphs, put no weight on the leader and successfully took a number of good fish from that section. My brain just never put the equation together and I "discovered" what y'all have probably known for years. I felt silly but will happily justify it in that a truth come upon is often more memorable than a truth told/read.
Just sharing.
