Upper Plum Creek is located in Walnut Grove who's claim to fame has to do with the famous author Laura Ingles Wilder. This county park is far removed from everything and because of that, wouldn't attract a great deal of users. I would think disc golfers would often have this whole park to themselves. There is a picnic shelter, restroom, play area at the beginning. And a large family/group was here enjoying a picnic the day that I played. The disc golf is completely seperate from the picnic facilities.
There are two sets of concrete tees for each holes. They are large and work well here. The baskets are great. This is a nice piece of park land for a course with water hazards, rolling hills and plenty of trees and thick underbrush. Intermediate players on up will be challenged by it's tight fairways, thick rough and sometimes small landing zones. Playing in a group or with spotters is a must.

This course is a formula for losing discs. It has blind throws over water, blind throws into tall grassy areas and thick brushy areas. Errant throws are almost always a long search or a lost disc. # 3 was a 270' uphill toss over a creek. It's scary even with a spotter. # 5 from the longs is a 385' blind hyser shot with almost no margin for error. A little off and you sail into deep, deep grass or thick underbrush. Without a spotter, I didn't even think about throwing it. # 6 is a short throw (less than 200') over a spillway with almost no landing zone. It's an invitation for a sunken disc.

#7 was my favorite but even it was an uncomfortable play. It's 450' downhill to a narrow mowed fairway, then uphill to the basket set in the trees with lots of nasty rough behind it. First I narrowly missed the narrow fairway and had to search and then I slightly overthrew the basket and was lucky to find my disc back there in the rough.

#9 is longish downhill (450') with the same narrow mowed fairways. I missed the fairway with my tee off and spent 20 minutes looking for my disc in the tall grass.

Yes, this is a challenging course. But I'm sorry, courses like this are not my cup of tee. I would expect to lost a disc a round on this course and that just doesn't sound like fun to me.

I guess if I lived in Walnut Grove and the next closest course was 20 miles away, I'd have to man up, play this course and increase my disc budget substantially. And add 30 minutes per roundfor disc searchs!
