Recently our course was redesigned and as such needed new signage. A friend of mine and I spent many hours working on them (me sketching the hole layouts and her converting it to an illustrator file). We also did a map of the course to go on the two kiosks at the start of each nine. They really looked amazing in the end. That was early this summer.
I just played the two course two weeks ago to discover that the plexy glass over the course maps has been shattered on one and chipped badly from a blow on the other. The first tee sign also has chips in it from repeated blows. To top it all off, someone spit chewing tobacco on the raw sign after breaking the glass. The kiosks are filling up with vulgar graffiti as well.
I was one of the co founders of our local disc golf club and am acting president. I have been operating under the mission of being a positive force in our local scene in the community and on the course. I am often encouraging the grounds-keeper/course designer who built the course nearly all by himself initially to not be discouraged and not give up...that we will continue to counter the bad element on the course with positive action. I've tried to encourage him along the way...even when two baskets were stolen and even when an amazing message board/sheltered bench he built himself was partially burned down because it was next to a garbage that someone started on fire.
Well now I see where he's coming from a bit more when I see my own project maliciously damaged/defaced. I'm usually up-beat, but this one is really bothering me. A few days ago I was tempted to say, "I'm done as a disc golf volunteer/ambassador in our community." I'm not in that place anymore, but I could appreciate encouragement myself at this point and hoped I might find it here among so many others that volunteer their time and efforts to make the sport they love better for others.

Has this happened elsewhere? Any ideas on how to stop it and raise the bar of accountability and stewardship?
