Pros:
Centennial Park has great DGA Baskets, 12 of them, and nice, big concrete tee pads, too.
The signs that exist are good enough.
Some holes don't have signs. More on that in Cons.
Lots of parking.
You could start this course from 3 places (holes 1, 5 or 8).
Its a good course to learn on. Intermediate players should enjoy honing their skills here, but more experienced players may not be challenged by what Centennial has to offer.
The fairways are pretty well defined with the possible exception of the longer holes (2, 3,7) where its just so very wide open.
This course is fun to play because its relaxing and easy to traverse.
The most memorable holes for me are:
Hole 5: Doglegs around the covered foot-bridge and over the stream.
Hole 9: Downhill shot through a tree-line, all while avoiding the stream.
Hole 10: Dog leg has you shooting under trees and over the creek.
This park is really well maintained; mowed often. The plentiful garbage cans at the tees keep the litter down, too.
When the season is full-on, there are restrooms at holes 1 and 8.
Cons:
The signs are lacking. Hole 4 was removed a few years ago when they installed an culvert for the small stream that flows through the park (which, by the way, improved the sogginess of holes "5" and 6 greatly) but was never replaced. Hole 5 is also unmarked for some reason, as are holes 10-13, but they are newer (added in the end of 2008, I think).
The layout could be better. There are a few long walks between a basket and the next tee that are so long they almost could almost put another hole in, from 2 to 3 especially.
Many of the holes don't have too much to offer: Straight shots, flat terrain, medium distance and few or dangerous obstacles like softball fields that are very often in use.
The brush and undergrowth around the stream on holes 9, 10 and 11 can get pretty thick and nasty. I try really hard not to go in there. I've found three disks on hole 9 (all unmarked).
There can be heavy pedestrian traffic on the playground equipment found on holes 6, 7, 8. I've seen players skip holes 8, 12 and 13 because of kiddy sports team practice.
Other Thoughts:
I think adding 5 more holes to make Centennial a full 18 is a real possibility and a good idea.
As is, the course is fun without being super technical and frustrating and a good place for beginners to get a feel of the sport.
I think redoing the signs would help many new players.
After you've played Centennial once its easy to find your way around for your next round.
