Pros:
Old Post DGC is has nice concrete tees at every hole, and good baskets too. There is often good changes in elevation. A handful of wooded holes, but mostly open and grassy with scattered mature trees. One hole with water in play. I really started liking this course once I got a few holes into it. It starts a little slow, with 1-5 crossing open grassy hills. 6-8 are more wooded, I really liked hole 8, uphill shot to a basket on top of a mound under a group of medium sized trees. Hole 9 gets back into the grassy hills, and most of the back 9 has a similar feel, but with a few more trees than the first few holes. Hole 16 is a downhill open throw to a green 3/4 surrounded by water (or at least mud). Very fun drive. 17 is also downhill, but much longer, with rough behind the basket. 18 is a long finisher, with a big turning dogleg right, and a mando at the corner.
Cons:
Some of the holes have too much open space, with very few obstacles. It is using what the park has to offer, but can be a little bland. It is long in places, but lacking some challenge compared with higher caliber courses. Hot weather and little shade make it a long hike in summer.
Other Thoughts:
Old Post DGC has several very good holes, a fairly simple and efficient layout that is easy to follow, and good quality equipment. I played one round passing through, and scored a +1 (3 birdies, and 4 bogies). If I made a couple of more putts could've been under par. This is a very good course with some really fun throws. Set in a very nice park that is well kept.
