Pros:
Great 18 hole layout in a beautiful park located in the heart of Downingtown. All 18 holes have concrete tee pads, signs at each tee, and arrows on the basket pointing you toward the next tee. The course winds along the East Branch of the Brandywine River, and features smaller tributaries that come in direct play on at least 3 holes if you're tight, and potentially many more with erratic throws. 5 short but tight, holes play through the woods, while the majority of holes are relatively open with strategic trees lining the fairways, complimented by a couple wide-open, grassy field shots. This course demands a nice variety of shots, and allows for some creativity in shot selection. While most holes have a fair birdie bid, I've had my share of double and triple bogeys getting off the fairway in the woods, or finding water/OB hazards. It would be totally appropriate for beginners, as it's pretty straight forward with not too much hazard in direct play (with the exception of #14) and relatively short holes, a great course for intermediate players to improve their skills, provides an opportunity for advanced players to score well and have some fun ace runs, but I bet the pros would light it up. I think it's fantastic use of a limited space, and a lovely walk in the park among beautiful old growth trees, the picturesque Brandywine River and bald eagles, blues herons, white tail deer and beaver are common sightings as residents of this lovely town park.
Cons:
There's a bit of a walk (just shy of a 1/2 mi.-10 min.+/-) from #18 basket back to #1/parking lot. With it's proximity to the river, it can be pretty muddy after some rain, but the concrete tee pads are a huge improvement regarding this issue. With the exception of hole #14, it's a totally flat course. The course winds along a walking/bike path, and you might need to wait for the occasional wandering pedestrian who doesn't realize they're in the middle of a disc golf course, but most of the time it's a non-issue.
Other Thoughts:
It's a young course with a good club backing it, and I believe it has has no place to go but up, as it gets played in and the "rough" gets thinned out a bit. Not sure if it's in the works, but it would be interesting to see this course develop with some alternate tees and pin placements in the future as is the trend with courses as they age. If you get hungry or thirsty during your round, there's several fine establishments within minutes of the course, many of which are course sponsors. It fills a niche of a high concentration of players, in a relatively low concentration of courses, and is easily accessible from the 30 by-pass.
