The start for this hole is between the green sign and the sidewalk. The target is not visible, but it is at the bottom of the hill (behind a number of large trees). If the shelter to the left is occupied, someone should be stationed nearby to prevent stray discs from hitting innocent bystanders.
Course Update: Since the metal bar shown above has been removed, the obstacle from 2004-2009 was the two small wood signpost stumps (about 1 inch high) next to the edge of the lake. Unfortunately these have worn down over time, so from 2010 and beyond the new obstacle will be the "no fishing" sign near the right side of the lake.
