Pros:
Flanacher Park is a long, beautiful 21 holes. Once I finally found the course I was impressed by the manicured open fields, and nice old trees. There are some good woods that some of the holes play through, some open field holes. But also just some wackiness (stay tuned)
Some of the holes were great. The fairways were nice, the pin placement creative, and the general forestry serene. I want to say I enjoyed that there were 21 holes, but then I remembered I skipped a few, which again I'll get to later.
One of the nice pros of this park is its secludedness. It's in a big park with baseball fields, soccer fields, a rec center, but there's not even so much as a walking path through the course. You're pretty much guaranteed to only run into other golfers, if anyone.
Cons:
This course has some weird holes. Hole 2 is the worst, but don't worry- the worst is out of the way after the mando-less 360 degree hole where the fairway is only 6' wide. This does start a theme of fairways that don't make a whole ton of sense to me.
One of the more frustrating aspects of this course is that it seems every third hole is a dog leg. Eventually I just started skipping them because I was just tired of 300 - 600 ft doglegs.
The grass off the fairway is SUUPER thick. It's actually so thick that if you throw into it you'll likely just land on top of it, and have no problem seeing your disc. It's the getting to it that's the hard part. Simile with the rough off the fairway.
Flat, but what you going to do?
The tee signs aren't the best. It was hard, even in open ground, to look ahead and figure out where the baskets are based on the tee sign (most baskets are blind, see above about dog legs and spinny holes).
Tee pads are small stone pavers that are kind of slick and uneven.
Other Thoughts:
The expectations going into this course were a little high, but they weren't really met for me. It doesn't get off to a great start, but it does pick up. For me, it was mainly just either a long open hole, or a long dog leg. If you walk up each fairway to where you can see the basket, you're walking every hole 3 times (once down to the basket, then all the way back, then playing the hole).
Hole 10 is my favorite hole because it's just a straight shot into a tight fairway. Holes 11 and 16 aren't bad either. But overall, it's hard to decide between a Good, or a Very Good rating for this course. I went with the 3 because there's obviously a lot of effort going into mowing the parts of it that get mowed, and the design isn't bad, but it's hard to rate an entire 21 hole course on the strength of a few good holes, when the rest are just what you would expect from a public disc golf park.
