macrabbit,
Okay, here is a picture as promised... In the gloaming on the incoming tide the fish wanted to come up, but there were lots of things to scare them away.
Just a short distance upstream there was a shallow riffle and the fish that had beaten the gautnlet had to get past the herons. With their backs out of water they gave themselves away and made it easy for the herons to lay a fly in their path.
Things that glowed in the diffuse light of the setting sun caught their attention and triggered wide-mouth takes.
My second silver taken a bit upstream from the crowd... The first was not terribly photogenic with a pair of large Vibrax spinners in purple and silver hanging...
Thanks again for the Aztecs!
