IF I'm catching and someone asks me what I'm using I will tell them. I might even tell them how I fish it.
Mostly I encounter bait or spinner folks where I go. They will say things like, "I tried that once." Or "I've always wanted to learn..."
I had a secret spot once, too. It was on a very hard to get to stretch of the crick and produced very well every time I crawled to it. Then I was talking to a acquaintance of mine who was a district Judge, he wanted to fish this crick and asked if I knew of any hot spots. I made the mistake of telling him. I even drew him a little map. Now there's a well worn path to the spot, the foliage has been hacked away and I haven't caught a fish out of there in 3 seasons. That was the last spot I've shared with anyone.
