Pros:
Playing a full 18 hole round will leave you feeling exerted. Par for this course is now 63, and the new lanes make you work to stay even. Excellent new signage and all of the new pads are very well built, slip-proof, and can't collect water. Nice mix of LHBH and RHBH-friendly lanes. This course gives you the opportunity to show off your huge bombs, either across the wide-open 600'+ fields, or down the 400'+ forest alleys. Plenty of solitude from Hole 5 to 17, but excellent water and bathroom facilities are never very far away.
Cons:
As mentioned before, First four holes seem like your standard city park course holes. The new lanes need the pounding feet of discers more than anything to help establish a path or two towards the baskets.
Other Thoughts:
If you have thrown this course before as a 9-hole, you will not be disappointed by the additional 9. A kid (and a phenomenal discer) made this his Eagle Scout project and the hard work shows. There were a lot of trees felled and a lot of materials used in making the pads.
Hole 17 is a doozy of a par 5 (668'); you need a very decent downhill drive with a sharp right turn. After which, the lane horseshoes back uphill and requires a VERY decent upshot for a chance at an eagle. After tossing 17, I'm always grateful for the Plain-Jane shot required on Hole 18 (old Hole 9).
If you're used to playing multiple rounds back-to-back, be ready to feel wiped. Bring a lunch and maybe plan to take little siesta before round #2 at this monster course.
