It is a multi-use park. Some weekends, you will have that other part taking over. Just as we look as a group to reserve the courses, and work with P&R, I am sure that the soccer teams do the same as well.
Be mindful, and don't get in an argument over the fact that it impacted a few holes. Let it go. Ask once and take the high road. We give in terms of sweat and blood on the courses. Most of these "fagball" types pay hard earned cash to get out for the weekend and play. It is their right to do so as well within the park.
Are they being gracious hosts? Absolutely not, destroying property though is an offense that should be notated, and discussed.
If we paid to play on the parks we would have more ammunition, but realistically, especially with a new course down the street, don't get angry, go be happy that countless people helped to put in a new course that won't have those concerns close by.
That is a large park with a big revenue stream from soccer, and ball fields, we are the little man on the totem pole. The Chief may not have spoken on the issue out there, but lets be better than those we need to interact with.
I for one appreciate your restraint for all of the disc golfers out here, many wouldn't have handled it as well as you did.
