Pros:
An apparently-forgotten course with little to offer.
-Amenities: Concrete tees, DGA baskets, minimal tee signs (like Lover's Lane).
-Solitaire: The park as a whole doesn't seem to get a lot of use, at least during the off season. This keeps it quiet, so it might be a good getaway destination.
-Woods: If you're into woods beauty and highly technical lines, Preston Miller might hit the spot. The majority of the course plays in very thick woods, where needle precision is necessary to carve up the course. Someone with a great putter game might enjoy it.
-Shot Shaping/Gameplay: A fair assortment of extremely tight shapes under 250'. This includes right-finishing shots, straight ones, doglegs left, and gradations of all of these. Mixed in are open holes on (1) and (11)-(14). This is a welcome reprieve with more distance (still mostly under 300') that allows more free throwing and a little bit of variety. On the whole, it will be a constant battle with the trees, which will inevitably win sometimes. However, being so short, scrambling will virtually always be a possibility.
Cons:
A little *too* technical.
-Lines: Frequently, somewhat unbelievable. The gaps sometimes resemble a walking trail, while at other times the twists can't be made with a single shot. Add to this that the margin of error is tiny throughout, and Preston Miller doesn't present an appealing mix for most players. The number of trees you'll hit will change any baseline plastic into a roller in one round.
-Length: I think there's one hole on the entire course that gives you the chance for a full send. Other than that, shots will be smooth and soft only.
Other Thoughts:
Preston Miller is here in the woods, and it's not the worst example of this I've ever seen. However, it has a long way to go to create a challenge with good lines. It's Reasonable, but nothing more than a woodsy pitch and putt.
