After being humbled yet again this weekend, in both CA and NV, I think it would be interesting to hear thoughts on why these fish, with so much cold water, so many bugs and baitfish, and so much fishy water, are so damn befuddling.

Not whining, cuz we had a great time as always, nor looking for tips, fishing spots or flies. Just curious on some observations about why these particular fish are what they are.
