Pros:
This course has two layouts now, forwards and backwards. When the course is reversed (backwards) the baskets are near the forwards tee boxes and the tee boxes are near the forwards baskets. This is a review of the backwards layout.
This course has good baskets, an active group of people who keep it clean and in good repair, nice trees (for Texas on the back nine when in reverse), trash cans, park benches at the start and on the course, a little pavilion near the first hole, ample parking when the school isn't in session, a couple of weekly minis, an active Facebook page, night golf opportunities, and locals who are friendly and who will show you around.
Cons:
The backwards layout has lots of problems.
There are greens where your disc can land within thirty feet of the basket and you will have no putt because of obstacles (This is true on reverse 2, 4, 5, 6, 7, 13, 15, and 16.).
There are fairways without a clear path to the basket (Reverse 11, 15, and 16.).
There are holes that are well above the ability of the typical disc golfer the course sees (16 for example requires an absolute laser shot 300+ feet long through some tight spaces at the end to an elevated basket that is birdcaged by a bunch of little trees, utterly ridiculous).
There are a number of blind par 3's (2, 5, and 14). There is a table and benches beside the 14 basket. It's an accident waiting to happen.
The reverse course was designed to take away overhead shots from the tee when possible. This often results in a single shot choice from the tee, a low straight shot.
Other Thoughts:
Forwards I would rate McClain a 4.0. Backwards I give it a .5. Since it is supposed to be reversed every other month (that was what I was told), I have to give McClain a 4.5 divided by 2 rating (a 2.0).
I'm worried McClain is going to end up like Live Oak when it's done being tinkered with. Live Oak does not have a set 18 holes that people play. There are 30+ holes and when people say they played Live Oak, you have no idea what holes they played.
Instead of reversing the course, I think more tee boxes and permanent alternate baskets should be added. If baskets are too expensive, put up tone poles until baskets can be bought.
Also, there is plenty of room for another 18 north of the current 18. Add those holes instead of messing up the ones that are there.
