As for discouraging: in the last 5 years that I regularly hike/bike Ringwood I don't remember seeing any rangers outside of Botanical gardens/Shepherd lakes area. They might venture into the woods unbeknownst to me, but then I guess they go undercover. Like riding dirt bikes, may be? Without any enforcement nothing could be done. Just last weekend I saw a car driving out of the Parking A and turning right, which is a wrong direction on a one-way road. Immediately next to this car there came a ranger truck that turned left from the parking and left.
