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.
