Pros:
The Centralia course has been doubled to 18 holes in the last year. But while the nine-hole version (front nine) was a decent park-style course, the new addition (back nine) introduces distance, several difficult wooded holes and a water carry.
The course starts near the end of the parking lot and is marked by a large map of the front nine at the beginning of the course.
Hole #4 is the signature hole that requires an accurate drive of about 225 feet over the pond.
The baskets have been upgraded from the original homemade baskets to suitable Monkey Trap targets.
The front nine features decent tee signs and concrete tee pads.
Cons:
Holes #5 through #7 run parallel to each other and some small trees have been planted recently, promising increased difficulty in the future.
Hole #9 requires a blind shot (possibly over the edge of the pond) without much of a fairway. It originally felt like a typical get-back-to-the-parking-lot shot; now it should be redesigned toward Hole #10.
The distances on the front nine signs are suspect on a few holes; no way is Hole #3 the listed 315 feet.
The back nine was not designed for the same audience as the front nine, and it's full of design mistakes. The wooded holes are very tight. Hole #11 requires a ridiculous line to get out of the wooded opening and then its basket is tucked into the woods. Hole #15 is uphill, nearly 500 feet, and plays near a fenced area marked by NO TRESSPASSSING signs and a pond. No way is it a par 3. Hole #16 includes a water carry over the aforementioned pond. Hole #18 is long, requires nearly a 90-degree dogleg left, and has a posted mando sign to avoid backyards of the neighbors.
The back nine doesn't have teepad or signs. You'll either have to spot the tiny flags or look for the well-worn dirt areas.
Other Thoughts:
Centralia added nine more holes, but that doesn't make the course better. Now it's a mishmash of shoehorned design and confusing challenges. The two halves don't fit and too many holes fall woefully short of good design.
