All that **** surrounding the whole course? Straight up marshland. Hole 7 and 13 have you throwing over the actual marsh, and if you go in, there's really no way to get your disc back unless it's not too far out, you can find some nice logs to make a jury-rigged bridge with, or it's hella low tide. Almost lost many a shoe fishing for lost discs.
Holes 1, 5, 6, 8, and 15 also have legitimate shots at going into the marsh, especially the ones that are on almost sheer, twenty-foot inclines dropping directly into swamp. If your course is as hateful as mine then I pity you.
