Unfortunately, most sites that have colorado fly fishing forums are huge nation wide sites. You dont get the same attention as you do here, this is why I mainly post on this forum. Fly fisherman also seem to enjoy solitude, which makes them less likely to share information. They are usually great if you meet them out on the river and will tell you alot about what they are hitting and different holes ect. But that from my experience is because you are already there no threat of bringing more people to that spot.
I'd like to see this fly fishing forum pick up, we just need some fly fisherman (unlike me) who know alot about the subject to start frequenting the boards. The more questions asked to more answers you get sorta thing.
