Tight twisty singletrack through tallgrass and trees with some short ups and downs into an old river wash. It's a good workout if you take a couple laps. It is usually ridden CCW, but switch it up for something new. This is city land and they are supposed to help us maintain it.
There is a big Dillon's store at Cloud and Ohio. Go east about half a mile to the flood control dike. Ride south on the dike about 500 feet then ride down the east side to a wooded area by the river. There is a chain link fence on the side of the whole trail area. Enter on either side of the fence.
