Pros:
This course boasts a great deal of variety, from woods holes, to a huge hilltop bomb, to an island green, and everything in between. The most beautiful view comes into play on the downhill hole #12 with views across the marina and lake to distract you from the sweeping left to right shot you need to execute there.
Starting at the kiosk sign in the middle of the marked disc golf parking lot, you'll find level concrete tees, trash barrels and seating where needed on the course, and you'll be shooting at Innova DiscCatcher baskets, where the large yellow band will help spot some of the blind basket positions with a short walk up those fairways.
Some of the early holes are fun temptresses, beginning with the hole 1 drop shot, which could be aced if you thread the perfect line through the tight tree gaps. The basket is up a backstop slope, so you won't run by. In fact, there are very few spots where risk/reward greens cause a huge gut-check (the obvious exception being the driveway circle island green on 17 - as played in tournaments). The summertime rough could be a disc concealer in the woods, and in the prairie grass on the later, more open holes.
An Intermediate to even Advanced disc golfer will find plenty of challenge working the variety of shots at Buck Creek. Early woods holes bring out your technical game, the breezes off the lake and the excellent use of elevation (especially on holes 11 through 14) will get your head in the game, and the bigger arms will get a chance to show off coming down the finishing stretch. There are fairways that demand very precise left to right lines (#6), and just the opposite (#8 in the uphill left pin position).
There are several signature holes here. I like the beauty of 4, 12 and 14. But one of the greatest 'pros' at Buck Creek is the beautiful scenery of this state park around an impressive lake. The wildlife drawn to this setting (deer, soaring birds, and everything in between) are wonderful to experience.
Cons:
The main issue I have had here is related to the beauty of the site (weird, huh?). There are going to be nature lovers all over this park. There is a lakeside hiking trail which goes from the marina parking lot on around, along the #10 fairway, and folks are tempted to hike up the ravine used for hole 9 and earlier. This is a hazard for the right-turning, blind #9 tee shot. Folks walk up the 11th fairway from the marina lot to the picnic zone (!) on (!) the 18th fairway (an unfortunate circumstance of dual-use space). I didn't see any signs warning non-players that they were entering a disc golf course (as if that would change anything). My last time at Buck Creek, there were maybe ten people in that part of the park total, but I waited for safe clearance four different times.
I have relatively little to complain about with the course itself, except that there are now usually two detailed signs at each tee, for how the holes are supposedly laid out now, and how the 'old' layout looked. These are intended to be helpful, but I thought they were sometimes a little confusing. The tight turners like holes 6 and 8 (upper pin position) aren't at all like either picture. Don't get me wrong, these are fun, tricky holes, but might really frustrate a first-timer.
Other Thoughts:
When your navigation system gets you to the park on North Bird Road / Buck Creek Lane, you've still got a ways to go: turn right on Park Road, and go (slowly: watch for deer) about a mile (half a mile past the sign for the Marina & Restaurant), to the sign for the Disc Golf Course (left). Go to the 2nd parking area on the right (that's marked for the DGC), and you'll see the kiosk at hole 1.
