You made the right call. Nothing pisses me off more than someone hunting out of my stand. It's wrong, plain and simple. Do some people just have no etiquette?. I'm glad you bagged him for trespassing. A lot of people just can't figure out what those big yellow signs mean. He for sure will never forget. Maybe he'll let his friends know the less than positive outcome from breaking the law. If not you've at least sent the message home with him.
