Haha. Old farts and their boat docks. Gotta love em. Sadly, I hear about this stuff a lot. And, in a way, I kinda feel for the home owner A TINY LITTLE BIT. The homeowner is wrong, but, I also know what's it's like to have a boat house that gets paint chpped off of it from dudes trying to skip jigs. And boats with "jig chips" in them as well. It causes monetary damage and it is wholely placed upon the homeowner to cover the bill. As for his grand kids fish? Well, that's just an old man being an old man. The old man did really take it over the top though. Shows he still has some spunk. And the fact that the local law inforcement only issued a warning also shows that the locals don't really care about bass anglers rights. I bet the officer sided with the old man when they were talking and probably had a bad taste in his mouth about forigners (non-New Yorkers), fishing their local waters.
Sounds like Mr. Menendez did the correct thing. Try to minimize the confrontation, report it, and continue on.
Eat. Sleep. Fish.
