A couple more things about yesterday. I had so many more fish rising to eat bugs in the film last Friday. A fella handy with a flyrod like @BilletHeadcould have a pretty good time. I figured out how to fool them with a trout magnet under a float and I really wanted to play that game some more. I did not get many chances on Tuesday.
On the trout magnet, color really matters. I purposefully played with colors and there were definite losers and winners. Some colors just would not get bit at all. Some got bit, but clearly not as good as my best color. On the Spring River, Black/Chartreuse (aka Bumblebee) was clearly superior. I won't die with a color. It will get a few minutes and then I'll move on to the next one I think might work.
