The dual tee setup for these 9 baskets is better than simply having a long and a short tee. In a limited park area, I prefer this type of dual tee design for a 9-holer. Some of the second tees actually do change up the shot by nearly 75%, so playing an 18 hole round isn't entirely awfully boring. One thought though would be to have the tees for 'holes" 10-18 be nowhere near the 1-9 tees. In this case, you could essentially play at each basket from to completely different directions so that each hole would be 75% different or more, except at the green, but you'd be approaching the green from a different direction anyway. Perkins park terrain and layout could allow this style - it would be nice to see. Like playing backwards through the course #1 tee to #9 basket, #9 tee to #8 basket, etc. Either way though, the dual tee design and playing 18 on a 9 basket course is a con because it introduces traffic problems with other groups.
Brand new baskets on a brand new course.
The tees signs were decent and fairly depictive, but I think some distances were off. The next tee signs are completely helpful and NECESSARY because you can see tee posts and baskets all over the park. Some of the next tee signs didn't point well at the location of the other dual tee.

The lack of meaningful and unique terrain at the park is the biggest con. It is simply a flat park, smack dab in the middle of a highly residential area, with a lot of mature trees. The design is such that sure some thought went into the layout, and thus the flow is okay, but really because of the makeup of the park terrain and features, you could take any given tee and move the basket anywhere within a 100' radius and you'd still have a similar disc golf hole. Same thing can be said oppositely, you could move tees anywhere within 100' or more and throw at the same basket for a pretty similar shot through tall mature trees with low branches.
Many of the low branches could be trimmed to open up alternate routes and primary routes.
9 holes disguised as an 18-holer. The reason this type of course design is simply a disguise is because the green area is still the same, so at most, you change 75% of the hole by moving the tee, and typically just change the first 1/4 to 1/3 of the hole. Although the tees are labelled red and blue, they do not correspond to PDGA skill level design standards, they just identify the back nine and front 9. Many instances exist where if a tee were moved just 25' in one direction or another, a second route would open up, or a higher skill level player may choose a different flight (over the predominant RHBH anhyzer hole design).
The tees are just natural right now. No problems with being not level because the whole park is flat, but they will become a muddy rutted mess soon.
The front tee marker posts (6' tall colored 4x4s) are spaced about 15' apart. This introduces a HUGE tee area which can drastically change the shot. This does not follow PDGA design criteria for maximum width of the front of a designated tee area.
Also, due to the dual tee design and holes actually labelled 1-18, because you're only playing 9 baskets congestion on busy days will definitely be a problem - who has the ROW?
The greens are wide open and flat - no risk inherent on the green from rollaways or tree protected pins.
Being in the middle of the residential area, and having the ball diamond really inhibits the ability to lose yourself in a round of disc and enjoy peaceful tranquility.
There is no water, no defined OB (except maybe the ball diamond if you get too shanky), no elevation, no unique terrain, no risky greens, no wide long wide open ripper holes over 450', no downhill bombers, not super tight tunnel woods, and just not any variety at all. Every hole is essentially the same.
I don't recall any restrooms that were nearby, but with the larger park I'm sure there were some within 1000' or so. There are no trash cans or benches on the course and because I'm positive the morons from the neighborhoods who can walk to the park and vandalize it will begin shortly, along with leaving hordes of litter (we sure hope not).

In trying to figure out how to rate this course, I had to go into my list of previously reviewed courses and do a comparison. Of the GB 9'ers, I'd choose to play this one last, overwhelmingly last. In comparison to Indian Creek which I believe has horribly underutilized some good park areas, I'd choose Indian Creek over Perkins any day! So, we're down to a 1 disc rating at best. Is Perkins as bad as the 0.5 disc courses I've played - NO! But it is so repetitive, so lacking in quality design that truly considers PDGA player skills and designs, and so "blah", that it is simply worth 1 disc only. Maybe some elevated tees, terraced greens, other gimmicky landscaping style attributes would add a little character? I don't know that the park itself will ever be able to offer much due to the flatness, right along houses, apartments, and a ball diamond. And just wait until all the leaves fall off all those trees - I hope the parks department mows and breaks up the leaves often, or discs will be a pain to look for. Perkins could be better by "creating" more design oriented holes with some branch cutting, tree clearing, and properly sized tees with some type of material, but the park will never yield anything better than a Typical course.
