Pros:
A beautiful, heavily wooded course that will test your needle-line shaping abilities.
-Amenities: Concrete pads, DISCatchers, tee signs including map.
-Beauty: One of the prettier courses for a suburban park. The woods are lush from the moment you get to basket (1) until the end. Very pleasant.
-Elevation: Big asset for a course on the shorter side like Suwanee. There are big uphills, big downhills, dangerous side slopes, valleys, and receding greens.
-Navigation: I seem to recall it being almost flawless my first play. Maybe a little confusing from (11) to (12) crossing the parking lot, but otherwise very self-evident.
-Shot Shaping/Gameplay: A gauntlet of tight and challenging woods holes. The distances are all under 300 feet, but there's still plenty to keep your mind occupied here. The shapes vary substantially, from straight to left and right turning to some doglegs and a split fairway or two. Combine that variability with the elevation possibilities, and Suwanee is mostly a non-repetitive course. Some ace runs, especially (8), and some holes that are going to be extremely difficult (like throw-ins only) to birdie for the 2. I'd say the difficulty is upper rec to low intermediate for the first 6 holes or so (thanks to steep uphills, particular curves, and substantial distance), drops off considerably in the middle of the course (which is full of putter runs), and ramps up towards the end with killer side hills and tougher lines.
Cons:
A flawed, heavily wooded course that may not care about your needle-line shaping abilities.
-Design: Some interesting curves out here. There are short holes that will be literally impossible to park, forcing a play for par. (10), (16), and (17) definitely fall into this category, as they all require either insane levels of turn or a turn followed by a long straight tunnel. (Expand those holes by 70% and you'd have nice, two-shot par-4s, but that's obviously not possible on the track of land.) Many other holes, like (2), (5), (7), and (11), are possibly doable but require some really creative and super precise technique to make it work.
-Forgiveness: This course probably has the most beatdown per foot of anywhere in town. Anything off from the thin line could go into unscramble-able territory. Paramount to surviving Suwanee will be the ability to realize when you can reliably make a shot and when you can't, and then laying up when you can't. These first two cons can make Suwanee a bit of a downer to play unless you're just nailing everything.
-Terrain: A workout when dry, a dangerous mess when muddy.
-Disc Loss: Definitely a possibility, mainly due to some blind shots down or along slopes. If possible, you'll want a spotter on at least (4), (16), and (17).
-Mono-Thematic: Suwanee Creek is a one-trick pony--short, technical woods. The only reason it holds my attention through 18 holes is that it's a pretty quick play if you're not searching for discs or ricocheting too badly.
-Length: The series of sub-200' holes in the middle is just boring, and almost enough for me to drop my rating by a half-point.
-Walking Path: Be careful and look before you throw.
Other Thoughts:
There are some things I like a lot about Suwanee Creek and some things I hate, and that's probably why the reviews on this site are so widespread and polarized. Overall, I think it's a cute technical course with a substantial number of lightly to seriously flawed holes. Going in with the expectation that you'll have to play some lame lay-up holes, I think you can still have plenty of fun gunning for the available birdies and enjoying the terrain. I'll stick with the lower end of Decent for now.
