I was in the lower part of the Canyon today (Sunday) for several hours and saw very few fishermen. They were probably all up on the Big T ... works fine for me. Lots of nice fish in the 10 to 12-inch range came to hand using an Elk Hair Caddis with a copper Copper John on a 24-inch trailer.
I got hung up in a tree and was trying to pull by leader free when I noticed that I was upsetting some local residents. Needless to say the tree scored my flies.
