Pros:
I'm going to be honest, the list of pro's here is short.
Firstly, the park seems to be a fairly nice establishment in itself. Disc golf was definitely an afterthought.
If you're anything Intermediate or higher, this will give you decent practice at up shots. Every single shot, except hole 3, is a straight shot with nearly zero obstacles and zero elevation. This is the definition of field work. At the very least you could dial in the distances on your putters/mids and fairways.
The course has nice signs and even has concrete tee pads (although they're way too small), but at least it's something dry to stand on...
The baskets are at least top of the line DISCatchers.
Cons:
The cons are a mile long, but honestly I'll try to keep it short because this course doesn't really deserve too much time spent on it.
Firstly, the overall goal appears to be to appeal to recreation players, as indicated by the exaggerated pars and overall difficulty of the course. However, I still think it does a fairly poor job at that. Most courses like that will not have anything over 300ft, whereas this course has several shots like that. Yea they may be straight and easy, but some are still long for the average rec player.
The worst thing about the course is how it flirts dangerously with other park amenities. Hole 3 is a prime example. The only "blind" shot on the whole course has you shooting up into a picnic table area that is around the corner from the tee pad. Additionally, several holes have you shooting across walking paths, courts and other fields that could be in use.
The park itself seems to be located in a flood zone. The entire area was soggy when I played and was holding fairly large puddles making several holes unplayable.
For anyone Intermediate or higher, this course will be extremely easy. You won't really challenge yourself and you likely won't learn anything about your game. The only reason to play here is to check off another course if you're a junkie.
Other Thoughts:
I appreciate the local parks and rec putting a course in, as I usually believe that any course is better than no courses, however in the case of Bethel Park, I'd almost prefer it not exist.
It won't appeal to anyone Intermediate or higher, it's slightly unattainable for rec players, it's wet and often dangerous. The only thing it has going for it are the signs, baskets and the fact that there's a dry spot to stand.
