I'm getting pretty sick of the majority of regular posters ribbing a guy for innocent questions. If you don't want to give info JUST SHUT UP AND DON'T GIVE THE INFO!
To make the point that they aren't just being "mean" or "rude" for no reason.
I find it hard to believe that anyone who fly fishes is rotten to the core and just inherantly rude.
Oh and I know all those rivers have been written up repeatedly, I read every fly fishing mag. like most of us. I know they aren't secrets, I have all the classic books like most of us.
I still am telling you all that there is a HELL of a lot of correlation to these good fishing reports online mentioning specific rivers and the hordes.
A report on this site will bring more people to the said river the next weekend than any magazine would. Try it for yourself sometime.
