no alcohol, littering or golfing?

Soooo me and Alex went to the beach the other day and as we were getting in our car to leave I saw this sign that was in front of a field on the other side of the road from the beach....all reasonable requests, no alcohol, animals, camping, parking, littering or fires. BUT thats not all, they also threw in no golfing, JUST in case you decided to grab your clubs and play a little putt putt in a huge dirt lot with fences around it....YOU KNOW YOUR IN HAWAII WHEN.....
