Cons:
Water hazards galore!
Don't recommend attempting to wade after wet discs...the ponds and ditches have 2 feet of mud at the bottom.
Other Thoughts:
The original (permanent) 9-hole course is relatively short (<300ft) and plays around a number of small ponds and water-filled ditches.
I played the temporary 21-hole course (which incorporates the original 9) set up for the Ohio Amateur Championships this year; that course is not for the faint of heart, or the wild of drive. Many, if not most, of the holes either played close to, or over, water. A number had pins well within 20 feet of the edge; aggressive shots that go even slightly astray will definitely get wet. Several of the temp holes were also quite long, 600-800 feet. Several people told me that after the tournament a year ago, more than 100 discs were fished out of the various ponds and ditches. (I personally fished about a dozen out this year, in about 30 minutes.)
If you play this course, don't use your $50 collector's discs!
