There was a new course installed in the St Louis area by Dave McCormack that recently opened. Since this park wanted to make use a lot of the wide open spaces it had to make there own non-natural OBs and obstacles.
For some examples see http://www.dgcoursereview.com/course.php?id=5936
Hole 11 for some man made ball golf like bunkers and small hill/raise toward the basket. Then Hole 12 has the same type of protective bunker in front of the basket. Hole 13 (not really able to see in pictures) is currently using stick markers for OB lines to create a fairway that must be followed. In the spring the grass will be mowed higher to more define the lines. Then hole 17 has both the man made fairways and bunkers with a protective man made hill before. And finally hole 18 creates a man made island style hole similar with wood stakes.
The bunkers are all played as OB, almost like small water hazards. Then the made fairways were played as re-throws with stroke if missing the red stakes (left side) and OB but take the distance and pull back in-bounds with stroke for the green stakes (right side).
It seemed to have a polarizing affect on people. Some loved the idea of making the open areas more challenging by adding the man made obstacles. Others didn't like the gimmick or ball golf like aspect of it. Since this is less than a couple weeks old, it may grow on people. Didn't know if others had similar courses or what they think of the course design.
