Pros:
This course is located in a 40 acre field of open grass and widely spaced trees, surrounded by a thin border of woods. You have a mixture of very open holes, with others that play into and out of the wooded border.
With two tees on each hole there is good variation of distances. From shorties like Hole 14 at 191' (obstructed spike hyzer) to the longest holes at an open 500'. You'll have the opportunity to drive with putters, midranges, and drivers.
With the exception of Hole 5, there are no completely wooded holes on the course. But many require that you successfully shape your drive to navigate obstacles either near the tee or around the pin.
I was surprised to see large trees being planted (by the city) on the course the day I was playing. Clearly they are being located in specific areas to increase challenge on some of the wide-open holes.
Holes 10 and 11 play to basket located on an earthen levee which gives a narrow landing area. No water in the canal when I played, but if there ever is the possibility of losing a disc is high.
Two teepads for each hole (labeled White and Blue). Most were concrete, with a few rubber mats here and there. Most positions had decent signs, though a few were missing.
Good Mach X baskets catch well. Hole 1 is elevated on a large earth mound, and several baskets are raised on taller supports to provide some elevation on this otherwise flat course.
Cons:
A busy walking trail in the wooded strip surrounding the course likely eliminated the option to place holes totally within the woods. So there are a lot of teepads tucked barely into the woods, throwing back out into the open field. Not great.
Course flow is odd. You walk out into the middle of the grassy field to throw Hole 1. Then over to the wooded border to throw to the Hole 2 basket, which is out in the open field. Hole 3 is back to a teebox in the wooded edge to again throw out into the field. And again for Hole 4...
After some more interesting holes into and out of the wooded edge, Holes 16 - 21 are located completely in the center of the 40 acre field, with open throws over grass. There has been some planting of trees very near the tees or around the baskets to provide obstacles, but you are playing in a giant field of grass.
Some of the concrete teepads were built on raised areas that are showing significant erosion, with some abrupt drop-offs. This could become a more significant issue if measures aren't taken to stabilize them.
Course is very flat, with the exception of a few raised baskets and the levee used on Holes 10 & 11.
I played on a cool, cloudy day in March. I imagine this course would be brutal in the middle of the summer.
Other Thoughts:
I'm not sure why the course was stretched to 21 holes. Holes 16 - 21 are very similar and don't add much to the interest or flow of the course.
After being away for several years I was pleased to play the two new 18-hole courses in the Rio Grande Valley. I found this one better than Dixieland Park in Harlingen, but not as good as Green Jay in McAllen.
