Pros:
Played 4 rounds in 3 days. Off the Blue & Red tee. Extremely technical course. Strong fairways within a treed forest with scattered rough. Mostly around 300 feet. Punishment for hitting the rough wasn't too horrible.
Riverside has 4 color tees. Blue, Red, Orange and Green. Blue is the primary. Red is similar, shorter and more technical. I imagine if I was a local and bored w/ Red and Blue, hey why not hit green etc? Each basket has a color code and a number on the pole, you just have to look.
Weekend traffic was pretty good, there are people around but the holes are separate enough that you feel isolated.
Cons:
There is cross traffic, and the people that I saw were pretty understandable about waiting for you. Patience for others is a safety must. A must need/have for newcomers - Maps out front. Pick the right color before you start.
Some of the baskets are out of sight or you can be looking at the wrong basket which is in plain sight but your actual basket is out of sight behind the trees. Newcomers, have to run out to the basket look at the color on the pole and double check the number so they KNOW they're throwing to the right basket.
Other Thoughts:
At Blue No. 17 is the only open hole, but you have to do a massive hyzer around a huge cedar tree, the parking lot is OB. Blue No.15. is over 600 feet, but nice to play. Blue No. 6 is right by the river, your choice red tee or blue tee. On the left there's a short steep treed bank, and it goes right into very fast moving Puyallup river. Don't lose your disc there stay on the fairway.
Across the park is a BMX bike course for kids. They got a drinking fountain over there. Also there was a flood a few years back, and the park is growing back nicely there's pockets of sand throughout the park.
Newcomers, watch for the white concrete entrance to the park on the right, painted on it says BMX Riverside, it's easy to miss!
