I've learned of a secret spot or two from other folks. The thing is, they'll say to me: "I'll tell you about this spot, but you can't tell anyone else". So I end up with a lot of spots that I can't talk about because others swore me to secrecy. 😀
Back in the day when I lived in Washington and there were salmon and steelhead in the rivers, people were extremely secretive, to the level of paranoia. And if you identified a spot on a steelhead forum, you'd get scorched because by golly it was everyone's secret that you just blew up.
I've found that usually when you run across someone on the water or at the ramp, they'll volunteer stuff they've figured out. I've always found out you'll get more info if you play dumb (I'm good at that).
