Sounds like a fantastic day out. I think one of advantages of disc golf could be that more tall grasses could be allowed to grow. We often worry about our forests but it is actually our grasslands that are most threatened from mono-cropping and human development. If we let them grow and allow ruminants to graze them but in rotation, they become fantastic carbon sinks and no animals are disturbed or insects poisoned and I think we could still maintain some short grass fairways for you disc golfers but you might have to fight gopher for disc back:)
