Glad you mentioned Pleasant Hill, the tees for holes #11 and #12 have signage stating do not go into the adjoining property (across the road) plus the property is posted with Keep Out signs. The property owner has already complained to the City of Pleasant Hill (thats why the additional signs are on those tees). The owner has agreed to periodically take discs found to the City, who will notify me and I will make every effort to return discs. So far the City hasn't called with any found discs (I know of at least 4 that have been lost in this field), evidently because players are going in for discs and keeping anything they find.
This is an older couple who haved owned this property for over 30 years, and do not have much patience with Savanah Land tourist turning around in their drives or disc golfers climbing their fences. We need to stay off of their property!
