RE:What do you do?!
I have my doubts regarding the SW fishing license. I'm afraid that only a small portion goes to fish resource management. It would amount to just another tax on the honest sportsman. Poachers aren't going to bother with them, and if a law isn't enforced, is it useful? In CA. striper stamps, Steahead tags and freshwater licenses are a joke. They are used only to generate $. Poaching stripers is so widespread that I feel stupid wearing my license, and don't sweat it when I forget it.
Oh, what to do...Take down his plate and maybe if the cops aren't too busy, they will enjoy dressing down the miscreant. Many policemen are avid sportsmen too.
One cast can change your day...maybe your life.
