It's a disc golf course.

9 extra holes seemingly vomited onto a previously decent 9 hole course. Safety concerns. Terrible flow. Poor signage. Clueless pedestrians.

Dirt Teepads.

This course is simply God awful especially considering the fact that there are so many choices now close by that are superb. It's a waste of time. Drive 15 more minutes north to McKinney if In the area. Alex Clark and Towne Lake both blow this poor excuse for a course completely away.

This is the first course I ever played back in the early 2000's. It was nine holes then. It was very playable and made sense. Now it is 18. A total waste of 9 baskets. It's unsafe with poor flow and dirt teepads? Come on Plano really? As big a city as Plano is with such a great tax base there is no excuse for such a craptastic course. Thankfully I have great memories of this course before it was destroyed by good intentions. Play it you have to but don't say you weren't warned. It sucks.

Variety of shots, elevation changes.

Layout is terrible.
Layout is dangerous.
Layout is confusing.

Fairways should never cross public pedestrian paths. Ever.
Tee boxes should never be in the previous basket's landing area. Ever. For any reason.
Fairways should not cross each other. Ever. For any reason.
If you can't follow the above rules and design the shots you want, you are building your course in the wrong place. End of story.

I also don't like seeing fairways that share space with playing fields (like the baseball field you have to throw across on whatever hole it is - 9 and 18 maybe?). Basically what you are saying is that the course can only be played safely when nobody else is using the park.

The confusing part is my own fault for not printing off a map beforehand, but I'm pretty experienced at finding my way around DG courses. Also I was in the area during the 2 weeks a year when it is wet enough that mud is an issue so I won't de-rate the course for that, but it would have been nice to have defined tee boxes with some sort of erosion control.

Hole 4/12 or whatever all it is supposed to be is just awful. If the tee box for hole 5 is outside the 10m putting radius for hole 3 basket, it isn't by much. This is just terrible course design and is repeated throughout the course. It's a shame because it is a beautiful park.
