I think sharing info is great as long as you don't go too far. I was fishing a good strech of a local river, and I caught a steelhead about 5lbs. and then a gentleman next to me caught a chromer about 9lbs. while three other fisherman watched. We brushed our fish and a drift boat came by and the man spilled his guts about everything. He told them of the fish we caught and the tactics we were using. The next morning, the place looked like Blue Creek. To say I was Pissed off would be an understatement. Sometimes people just need to shut their mouths instead of giving away secrt holes that they they worked hard to find.
