One interesting hole at La Mirada, Ca is #6 on the back 18. It has a wide, snaking concrete curb (level with the grass) separating left and right sides of the fairway and R is OB so you have to gauge your L/R line based on estimated distance. Then, the L side of the curb ends 50' from a basket 'island' (again using curbs) on the R with trees on the R blocking anything more than a 75' approach so the approach becomes interestingly risky based on your intial drive.
A rather cheap way to spice up an otherwise average hole.
More discs is more better
