You clearly have a much more rosy picture painted than some. Perhaps you and your intelligent friends have missed a few key indicators that things are a bit out of hand:
5 years ago I watched 2 guys just about roll into the water because one guys line tangled the other guys for the thrid time in an hour. I didn't appreciate explaining to my 6YO that sometimes adults are not very adult. It did offer itself to some interesting conversation but I don't think that's the type of memory I want my son ewalking away with. I may get him out again this year but will not make it the biggest priority. We fish a lot all year and this is just another day.
That's tame compared to some of the other things I've seen when out sans kids.

I'm sure others have some good stories of antics that have been witnessed.
