Pros:
I almost gave this course a 4.0 rating because of the incredible creativity in making nearly 18 distinct holes despite having only 9 baskets, but I've only given that high a rating to one 9 basket course (Mason Sports Park - please see my review for why). So this 3.5 is given for Clear Creek being an amazingly well thought out, and very fun course.
Situated in a smaller community park less than a mile from the heart of town, the designers had to work around basketball and tennis courts, a baseball field, a large parking area, playgrounds, bathrooms, electrical equipment, and other features, so they chose to put in nine really neat basket locations that afforded interesting shots, rather than attempting to shoehorn in more (weaker ones). There's a basket raised on a pyramid of tires, another on a mound, and one brilliantly placed in the middle of a spreading, large, triple-trunked tree. They initially laid out "short" tees totaling just under 2000 feet for the 'front' nine, then added longer tees for a 3100 foot 'back' nine, where almost every long tee is drastically different from the front. The tees are enormous trapezoidal concrete where needed, but vary to reasonable concrete and even all-weather turf, where that works well. Signage is tremendous at all 18 tees, indicating distance, details, mandos, etc., and there are next tee signs where necessary.
Tremendous use of elevation gives you four uphill holes, three downhills, shots that finish left, right, and straight, shots that use a moderate amount of trees to define the lines needed, short ace runs, and bombers that go as long as 438' uphill a good 30 or 40 foot rise. All this means that skilled players above the Intermediate level will need to get their deuces early, because the later holes will force really good play to go under a three. Casual and Recreational players will appreciate the shorties and ace runs.
There is a practice basket, and benches, picnic tables, & trash receptacles are available on or near the course. Did I mention the baskets are locally hand-crafted, and improve a little on the Discatcher style in that the top ring has a narrower band? Signature holes include the sweet short downhill 3(12), the short, but double mando'd hole 7, and I think hole 17 has to be listed as unique, gunning over 400 feet from the corner of the park, through the tree gap, downhill over the creek, to the tree basket.
Cons:
For a smallish Midwestern town, this little park has a bit of an 'urban' feel to it, with a number of activities crammed into a relatively small space. So there will be a lot of times when non DG'ers will be in the way, from the summertime (all over) to the winter (sled hill on 4(13).
There are a couple of places where the flow is awkward: walking all the way back across the 6 (15) fairway and the parking area to the 16th tee, then around beside the road, across the bridge (and back) to tee off on 17, and the fact that the 17th tee shot goes straight over the heads of those on the 18th tee. There might be a need to add some stairs on the hills down 3 (12) and leading to the 18th tee, for when it's icy or muddy. (But the payoff is some really sweet holes, so, just use caution and enjoy).
Other Thoughts:
The local disc golf club is growing, and actively installing courses, and they seem to be pretty nice ones. If you're traveling through along I-70, in the very near future, you're going to have a fun set of places to stop and get a round in (New Creations, Clear Creek, and soon, Glen Miller).
