Very interesting article on Terrestrials! Everything that "Tom Travis" said for the "Yellowstone" can also apply to your favorite waters.
Al Campbell explained that instead of rushing to the edge of the stream and start casting, it is better to sit on a high point away from the stream and just observe for a few minutes. Over time spend in observation, you will start to see actions on the water surface that you might not otherwise have notice. When the hatch is on, definitely go dry fly, attempting to match the hatch, but when there is no hatch watch to see what else is happening. As Al Campbell told me "Let the Pretty Girls show themselves!" Same applies to Terrestrials. Grasshoppers or Crickets in the grass, if you stomp your feet they will jump. Some of them might jump into the water, and instantly be consumed by a fish waiting for this to happen.... ~Parnelli
