Jon and I took guide school students Dan & Dave to the McCloud today to work on freestone skills.  The river is really high and only marginally fishable, but it is clear and there are lots of bugs around in the afternoon.  We saw lots of green drakes, a few golden stones, and some large PMD-ish mayflies.  The fish weren't too interested in rising, but in the afternoon the nymphing was really good.  A size 10 natural hare's ear was our best fly.  Dan and Dave both hooked some really nice rainbows.  Dave guided me into an 18" rainbow, but it didn't stay on very long due to some guide error (I won't say if it was me or Dave!).  Flows should be about perfect in a week or so on the Mac.
