I don't have a picture, but if anyone out there has played Forked Run in Reedsville, OH, they know what I'm talking about.
The hole runs on top of a man made dam. 225 feet dead straight, but the fairway is no more than 10-15ft wide, and drops off 30 feet into water on the left and 50+ into the valley on the right. I've never seen a hole like this before or since, and I like holes that are really difficult to play but also have no trees or obstacles, seems like the most difficult thing for a disc designer to accomplish. Always wanted to find a course that was lynx style, like the British Open in golf, where there are no trees, just extreme elevation changes, crazy winds and deep rough.
Others, once again no pics sorry but I love this thread:
#16, Sharp Springs, Smyrna, TN. Picturesque swamp-like hole has every shade of green in the spectrum, explosive foliage. If only we could kill all the mosquitoes...
#17, Lake of the Sky, North Lake Tahoe, CA. Plummets 50ft through forest surrounding the most beautiful lake in America, great veiw of lake from teepad.
#3, Sugar Bottom, North Liberty, IA. When this hole gets flooded on hot days in the summer it is a blast to play.
