This second fish had a few lessons to offer:
1: After catching a fish from a prime lie, don't count it out without giving it some more attention. There is often more than one fish there, and your catch may not have spooked the others!
2: A slow approach into terrain that limits the trout's sight lines (like a rocky riffle) can put you into very close proximity to fish. The broken up surface and "compartmental" nature of areas with larger rocks are an excellent opportunity to get into great casting positions.
