I've had a great couple of days so far with Mike and Kay from San Mateo.  They're at Clearwater Lodge doing a private Mastering the Art of Fly Fishing class.  We're starting from the ground up, with casting, entomology, knots, gear, and plenty of fishing.  We spent some time at Cassel Forebay today sight-fishing with nymphs.  The brook trout are surprisingly wary, but we got quite a few grabs and landed a few fish.  On to Fall River tomorrow...
