Pros:
Well thought out course with a variety of interesting holes. The course makes good use of the trees and the meandering creek. Each hole has a relatively new tee pad and a sign showing the hole and usually an indication of the next tee as well. Garbage cans on the first few holes, but you only have those adjacent to the park pavilions for the last 2/3rds of the course.
A couple of long holes (580 ft+ and 700 ft+) and a few < 250 ft for variety. The majority of the course is in the lower 300's or lower 400's. The course follows a logical progression around the park and was fairly easy to navigate with the map (I got mine at the gas station next to Dolese, but there needs to be an updated map online somwhere) and the indicators on the signs at every hole. A few holes even had "Next Tee" arrows on the pins or near the pins to help navigation.
Vast majority of the holes are laid out in a predominantly East/West direction which can cause havoc in a Southerly/Northerly windy day.
I've mostly played on a Sunday and the park is not very busy. Could be a different story on a Friday/Saturday, especially in relation to the soccer fields (see below).
Cons:
All but 2 or 3 of the new tee pads are TINY. Like about 5 feet long. Basically more than one stride, less than two. That's probably sufficient on the 180 ft to 230 ft holes, but those 300 and 400+ holes need full size tee boxes so that golfers aren't worrying about rolling ankles on the step up/down as they stride onto the boxes for their drive. Might be better to just throw from the ground adjacent to some of the boxes. The two long holes have full-size boxes, but the middle distance holes suffer a tad from this deficiency.
Like most open OK courses, wind is a huge factor. With the vast majority of the holes laid out in a predominantly East/West direction, this can cause havoc in a Southerly/Northerly windy day. A little more variety as to compass rose orientation would help even out the course on N/S wind days.
A little bit of a hike is to be had between holes 8 and 9 and 11 and 12. The lack of a bridge over the creek makes navigating 10 thru 16 a little tricky at times as well. 17 and 18 are layout out parallel to Route 66 to the north and well-utilized soccer fields to the left. Wouldn't recommend playing those holes on a Saturday while games were going on. 2 is in pretty close proximity to some soccer fields as well.
The online map linked at this site bears no resemblance to the course. It needs to be updated. The club that appears to be maintaining/upgrading the course (Route 66 Flyers) has little online presence that I can find and didn't have any luck finding links to any current maps.
THERE IS A BIRD THAT WILL TRY TO ATTACK YOU ON THE FOURTH HOLE!! Come prepared and bring a spotter to watch your back while putting.
Other Thoughts:
I vacillated between a 3 and a 3.5 for this course. Gave it the higher score mainly because the only beef I had for this well-thought out, effectively-utilized course was the tee boxes AND THE ATTACK BIRD.
Walking the course for the first time, I also felt that there was a missed opportunity for a hole that could effectively utilize the park road as O.B. between the pin at 11 and the bridge to 12. Would have worked well with the flow and kept you from walking a ways to get to 12. Still, that's just opinion and doesn't detract from the course.
Overall, I enjoyed this course. It appears to be well-maintained and is in a good location relative to OKC. It offers a variety of shots and is just beginner-friendly enough not to be frustrating. I will play again.
