Well, I've been flyfishing for 50 years, and I still wear polaroids, as much for the ability to see hazards on the bottom as to spot fish. My Orvis Rod is going to expire the guarantee pretty soon, and my Orvis vest (a gift from my wife) is about 15 years old now, so I am not exactly a fashion plate on the river. So much Orvis because they had a shop here, and for a while I worked there, although with that job I didn't make enough to afford their products (I guided the Editor of the News and the head of the school on the LO tribs using a Glass St Croix before they became chic and trendy). We've always seen big crowds around run peak times ( Mid September used to be the bigtime, now it is Columbus Day and around Halloween.) But now it is sustained from September into November. As to the roll cast to the same spot, once you know what the right water speed looks like, and you pick out a seam, especially in high water, you will connect a lot more by keeping your fly swinging through that same spot, usually on a pretty short line, than you will glory casting all over the river. However, even at 2000 earlier in the year, a 5 and a couple of 3/0s' was plenty of weight for this fishing, and that is a lot less than a small marble. As to competition and numbers, it is all official now, check out a couple of Morgan Lyle's recent articles about Loren Williams (who used to frequent this site) and the competitive trout leagues that are starting up around the country.
Early morning blathering, now off to work...
