Pros:
This course earns many points for being the only 18 hole course inside the D.C. Beltway. That said, it's hard to write a review for a course like this, because many of the features that make it great for beginners or for practice rounds make it mediocre for competitive play... so I'm going to put most of the course description and playing information in the "Other Thoughts" category and use the pros/cons for very basic information... so skip down for the thorough review.
But in brief, the pros:
Decent concrete tees on every hole
Multiple tees on many holes; where present, the white/blue tees add difficulty and give the course a higher replay value.
Large, beautiful trees provide great shade in summer.
Very little underbrush.
Good parking, and convenient location inside the Beltway.
Amusing course and highly playable year round.
Friendly locals and a decent club host several tourneys every year and often try new/different formats for fun.
Cons:
Doesn't drain as well as some courses, so it can get mucky in places after the rain.
Fairways are close to one another without a lot of tree protection, so watch out for flying discs.
Shot variety is weak -- many holes give you that "deja vu" feeling.
Almost zero elevation change.
Other Thoughts:
I would rate this as an above average red/beginner level course, but it's not so great for other level players. Though it is a very good place for more experienced players to practice new discs and throws with minimal consequences... ideal for practice rounds with mids/putters.
The tall, beautiful trees that provide 95 percent of the obstacles here have very few low branches, so there is very little in the way on most holes. The trees do force some minimal line-shaping, but because of the lack of low branches, there is a high-ceiling available on almost every shot, and even when you hit a tree, there is seldom any significant penalty for it -- you just have an open 2nd shot toward the basket.
Most holes have half-a-dozen different lines to reach the basket, and most of the distances are in the 180-300' range. So there is not a lot of variety on the holes, unless you choose to FORCE some variety by trying different lines every time and trying different discs, different routes, different types of throws. In this sense, this course can be great for practicing your game -- it's just a very poor course for competitive rounds...
Based on PDGA tourney results, scratch golf (1000-rated) is in the 40s for every layout, even the hardest tees. From the red tees, 1000-rated golf requires shooting -12 or better (42 strokes for the round), which just isn't an ideal tournament venue.
Bottom line, the short, open holes and the lack of OB/bushes/thick-trees/elevation/etc... to penalize errant shots makes this ideal for beginners and practice rounds but weak for any sort of competitive play.
