Yeah, I'm not saying that everyone does share their honey holes - we all know that doesn't happen.
My point was that maybe if people did share a little more with newer anglers we would see even more people take up the hobby. I mean really, what's it going to hurt to put a new angler on more productive water? I know a lot of people try to keep things secret on a lake, but let's be honest. Unless it's a tiny private lake that no one else has access to -- then someone else has fished your spot. And chances are there are plenty of other "honey holes" around the lake which others are trying to keep as their secret -- which you've fished.
Besides, most of the veteran anglers are not looking for people to tell them where exactly to fish on a lake {if they really want to know, they will just hire a guide and voila} - they may be asking for where the fish are in terms of spawn, or maybe local info on what type of bite is on -- but most vets I know are looking for information to build a pattern from, not a specific point off the edge of a flat on the bend of the old river channel. A few mins with a map and you'll find that anyway. But having a heads up on the water temps, clarity, level etc etc gives you a much better chance of starting out in the right places vs pulling up to the ramp and beginning from there. For a vet, that should get them started. But what if you've only been fishing a few months?
Chances are the same info in the hands of a novice would give them little advantage as they probably haven't been studying patterns for years or have much experience to draw from. That's when saying, "Hey man -- yesterday we were catching a ton of fish in cove "X" doing "this". They may not still be there today, but they should be close, just look for the shad ..." or whatever. Setting them up for success, but giving them enough room to learn along the way.
I don't know, maybe I'm crazy... maybe I share too much. I do, however, agree that if someone is hurting the fishery by removing lunkers or damaging / littering the area that I won't share again. But, I've yet to have that happen to me personally (but I know it absolutely does happen). Generally if someone asks me about how or what I have no problem sharing.
