Pros:
A nice disc golf course with well maintained fairways and decent challenges. On almost every hole there are trees or telephone poles to navigate around. The course is rather open due to its location in a park and access roads running through, but a lot of time and care has gone into the management of this course. I played it a year after the first reviewer and it had only improved. Signs with hole locations are posted at every hole, scorecards and pencils are available at the first tee, and the zoo staff can provide map with the course location and layout. Tee boxes are not concrete, still red gravel.
Crowds are definitely not a problem here, as we were the only ones on the course the first time and one other group the second time.
The first tee is located across the road from the pool/water park and kid's camp with ample parking.
Cons:
Holes are a bit short, but challenging. Rough can be very rough as there is tall grass in several places, in one instance 5-7 foot reeds growing on the left side of the fairway on hole three, with heavy underbrush. Almost lost a disc in there.
On a couple of holes you have a lengthy walk to the next tee, but each hole is marked well and easy to find. Really, though, those are the only downsides.
Other Thoughts:
I was pleasantly surprised when I played Pioneer Legends. When I'd heard that Scottsbluff had a disc golf course, I was excited because I'd grown up in western Nebraska, but was expecting a course similar to Yellowstone where the holes are not marked and you're basically throwing at trees or boulders. Imagine my surprise when I saw the signs, actual chain basket holes, and cut fairways. It was really a great experience for me, but alas, I was home on three weeks' leave and didn't get to play as much as I would have liked.
I highly recommend playing this course if you ever find yourself in western Nebraska or disc golfing across the U.S.
