Pros:
Rose Park has some unusual holes, and does well fitting 18 holes into the nooks and crannies of a small park that has a lot of other stuff going on. There is a playground, high school athletic facilities, a pond and some picnic shelters. None of them were being used when I played there the day after Christmas, save for a gentleman walking laps on the track.
Expanded from 9 to 18 holes, the tees are all concrete and have signs, and those DGA baskets with deep buckets were all good. There bright spots throughout the course, with some water, woods, elevation, and long par 3's.
It begins with hole 1 near the playground as you drive into the park, very easy to find. A decent starter that is discreetly slanted downhill and has a couple dozen trees as you get near the pin.
Hole 2 is a hard dogleg right with thick rough if you cut the corner too tight. 3 is a good one that has a straight shot to a clearing before fading sharply left once you enter. It also has thick rough if you get away from the line. Neither are easy birdies, especially if the wind is out in force.
Hole 7 doglegs hard to the left, and is guarded by trees and tall grassy bushes. Number 8 is very high risk and reward, with a pond on the right, and steep drop off into dense growth to the left of the berm.
10 is the most crazy, toughest hole, and I liked it the best. The fairway bends left before reaching a bridge, and the basket is to the right once you get across. Getting across the bridge is not easy, because there is water to the right, and mushy grass where the water makes its way toward the pond on the left. Both sides of the bridge have many trees, chopping the approach into a slivers if you are not right at the front end of the bridge.
12 is long for a par 3, and there is a train caboose on the right side that I hit with my terrible second shot. I have never hit a caboose with a disc before, I wouldn't recommend it.
14 has the largest elevation change, dropping off the side of the road about 20' pretty quickly, and a big tree waiting to catch any disc that flies too far to the right.
17 was a fun hole that is shielded by tree branches down the middle, but has a left opening for the RHFH hyzer, or a smaller tunnel to the right if you want the RHBH hyzer. I mistook the basket for hole 4, which is visible down the center of the right hole, to be 17. It would have been a great throw had I been right, but it wound up costing me as I blew the comeback and made a bogey.
18 is in some thick trees as well, it bends to the left and is perfect for a RHBH hyzer if you can avoid being knocked down by all the trunks, stumps and branches.
Cons:
I don't remember playing a course that crossed roads so many times. Holes 1, 6, 12, 13, and 14 all do it. May not be an issue most of the time, when if the park is host to sporting events, practices or picnics, it could be frustrating.
Some of the tees were pretty small, I like them to be larger myself. 8 and 10 have significant chances to lose discs in water or rough. 11 and 12 play close to the shelters, dangerous if they're occupied.
Other Thoughts:
It isn't the strongest 18 in the state, and has some definite issues. Probably several holes that become unplayable if there are lots of people, and cars parked in the lot.
However, Rose Park does have a full 18 now, and I would think the rural location doesn't draw a lot of traffic most of the time. I'm guessing holes 6-14 are the new holes, and you could skip some or all of them to shorten it up to 9 or 11 holes.
Hitting the caboose on 12 was a new one, but another weird thing I had never seen occurred on hole 8. My brother in law turned over his driver straight into the pond. We were able to retrieve it without getting our feet wet, because the water was frozen. Not solid across the entire surface, but that edge appeared to be shallow. I was not totally confident it would hold, but couldn't leave his plastic sitting there in plain sight. It slid 25' from the edge, but I was able to scoot out there slowly, and slid it back reaching the last few feet with a stick. I guess that is as close as I will ever get to playing ice hockey.
The wind was killing it that day, and both of us were shut out from getting any birdies all day. I had a putt on 15 but missed it, and he had a good look on 18 but could not convert. I was 11 over par (65) at the end of the round with 2 double bogeys. Extremely frustrating, everything that I threw hard was highjacked by the wind, and there were not a lot of good drives from either of us.
If you are running out of new courses to play in the area, this is not a bad option. I will likely come back and try to post a more respectable score eventually. Just not until I get a great weather day, or at least a day with no wind.
