Worst course

What has been your worst trash experience, what course and what did you do?
My home course is a rather ignored 9 hole course right behind a school playground. It's not so much the little kids that attend school there, it's the teens that walk through on their way to the corner store. They come back with food, drink or whatever, leave the trash, carve up the picnic table and trash a basket or tee marker.
The course have been mistreated for years and isn't maintained at all. All I do is pick up the trash I can and try to discourage poor behavior.

Trash seems to be a problem every where.
On the newest course that I installed in a public park, there seems to be a bud light drinker out there leaving cans,
Hope to some day meet up with this person to discuss their problem.

We have an awesome course in Fort Worth called Z Boaz. One of the best courses in the entire state. Except it has a huge problem with trash. There is so much that the local players can't even seem to get a handle on it. There are alot of younger players from the area that just don't seem to get it and everyone you talk to about complains but doesn't seem to do anything to help fix it. The trash cans hardly ever get emptied because they aren't where the city has easy access to them. As a result, they are all overflowing.
The local club even put in recycle cans for aluminum only but people seem to think it's funny to throw whatever they want in those as well.
I believe 75% of the people that play here have never heard the phrase "pack out what you pack in".
