We haven't had problems with it around here, but all our courses in parks are permited. Though if I remember corectly the original tones at the Redwood Curtain were cammo sence the course was not permited yet. Cammo tones might be the way to go that way you have less chance of people noticing them. They will be hard to see untill your up close, but it could help from atracting unwanted attention. Just make sure to use a part of the park that doesn't get much pedestrian traffic, nothing will mess up a new course like some dink geting hit with a disc. Best of luck! I hope to play your course one day.
