First, take care of that back. with several days of fishing ahead, you'll need it. I am sure there will be plenty of good flies to go around, and sometimes the ugly ones are best anyway. Last week, my friend had one of his best days fishing this year wit six caught, several that got off, and one big one that broke his line. I stood right next to him and caught nothing. so yes it is possible to get skunked even at home, but with several days and locations to try I am confident everyone will catch fish. The trout are in the shallows right now, and I saw someone catch a nice snook the other day so they are around too. As of today, the forcast for friday is 70's and lots of sun! Not too hot, and not too cold!
PS. I am too excited for sleep too!
