Pros:
This course has an excellent variety, and it is very attractive for every skill level. There is really not a rough, so bad shots are not terribly hard to recover from. Beginners can probably enjoy this course, because it's not too punishing. However, intermediate players will find some challenge and even pros would probably enjoy a round here.
The trees are used very well. Also, the creek is in play on several holes and adds some extra challenge.
Baskets and tee pads are in fine condition. There are restrooms, water fountains, discs(?), and a course map (?) in the gym. I didn't check that myself, but that's what I understood. A walking trail, along with the gym and tennis courts give a variety of other activities. There is plenty of parking.
Cons:
Several signs are missing or damaged. Navigation is pretty easy on most holes, but could be made easier with a few well placed signs.
I don't like playing by a busy road and a couple of holes play along a road. Also pedestrians on the walking path could occasionally interfere.
Other Thoughts:
All in all, McClure is a very enjoyable course. It offers several challenges with no severe punishment and makes for an enjoyable round. A big arm would have several birdie opportunities, but very few easy ones.
Tulsa is an incredible disc golf city. McClure is one of the best courses in town. Definitely a good choice!
PS If you have time for two rounds, play here twice. Don't waste your time driving to Dovillio.
