lv2nymph,
Absolutely. My personal opinion is that we should all share 100% freely. Famous waters are famous for a reason, but they get OVERFAMOUS because of the stance that's it's ok to talk about streams everyone knows, but not ok to talk about the lesser known ones. We don't have a problem with too many anglers in this state. We have a problem with overconcentration of anglers. Stream X looks like a zoo while there's tons of other very good streams that go lightly fished.
As someone said, this is circular logic. Don't spotburn the lesser known streams. Which means all that we can talk about is the well known ones. Which means singling them out.
That said, I value friendships more than my stance on this. If I have been shown or told about a stream, I may discuss in person or via PM, but I tend to keep it hush on the public board out of respect for the person who informed me. Lately, really, I tend to shy away from giving lesser known stream names publicly, regardless of how I learned of the stream. I think that makes me just another person contributing to the problem outlined above. But it seems to be the unofficial semi-agreed upon law of the community, and I am a member of the community here. Follow the rule to prevent fights, while advocating for change.
Via PM, I'm an open book. If I don't know the person well, I will generally give dozens of options, though, rather than highlight one.
