#8 yep. Not naming names but I took someone from this forum several years ago and I know that they are now a regular at that lake. I don't care because I have only hunted there maybe twice in the last 8 years. But lesson learned for sure.
What did you expect, that lake would be off limits to him for the rest of his life? I try to get a friend to hunt with me on a particular lake, he will not do it because another friend introduced him to the lake for the first time years ago. While I admire his loyalty, that's just stupid. You hunt public long enough and you know all the lakes and all the spots. It's more about finding birds during the season than spots.
I took Larry hunting on a lake he never hunted like 2010 or so then few years later he said he never hunted that lake again because I showed him. I said good grief go hunt that lake and spot all you want. If I was worried about it I would not have taken him. I took a newbie hunting once, he hunted that same spot all season, just what I expected him to do.
