Of course, it's only funny because you didn't suffer any damages. We had a little incident ourselves a few weeks ago... we live on the north side of a golf course, and a small strip of woods separate my house and the 16th green. We had about six little juvie delinquents park down the street, walk through my back yard and hit the course.
The police were waiting on them when they emerged from the woods with tee markers in hand.

We called the course owner, he pressed charges and they got to spend a comfy night in the county jail as a result.
This is exactly what I am talking about. If they vandalized the golf course and tore up the greens or something, by all means, prosecute. But if it a group of kids that were just trying to sneak in a little night golf, come on.
Make them pay, make them work so many hours at the course, scare the heck out of them, but don't give them a record for something like this. Just my opinion, but just remember that most of us have, will have, or already have hadteenagers,and some daythat same standard may be used against your kidas well.
And no my kid has never been in the least amount of trouble. He takes after his mom. But he is still only 15 and if he only does half of what I did when I was that age......well it ain't over yet.
