Mother Nature certainly has been teasing us this year.  Either this year is going to be a very light emergence, or most of the caddis are yet to come.  I saw maybe a couple hundred below DePuy's and a few here and there in town.  Keep forgetting the thermometer but its got to be close to 52 or better.  The good news is the river is in  great shape, plenty of visibility for fish to eat dries.  Sometimes the fishing is actually better when you don't see a ton of bugs.  Look for fish working the edges of the rip rap and row hard to get your buddy some good shots.  If you see a fish taking caddis, you should be able to force feed him within 4 or 5 casts.  Since the water is pretty clear right now, try to cast well down stream from the boat to avoid a big fish seeing your approach.  Often the best move is to pass a rising fish, pull in below him, get out and throw a few casts over his back.  Chances are you'll stick him right in the nose!  Don't forget some high vis patterns, the fish will be eating dries well after you're squinting in the dust to see your fly...
