Probably Bismarck's best secret.  This long singletrack is looped like a tapeworm into the grounds around the Adventists Academy.  It utilizes steep embankments and natural ridges well creating a trail full of moderate climbs and wrist numbing descents.  Much of the land is actively grazed by cattle so please respect these animals and the land.  It is a great privilege to have access to this wonderful private stash.  While the trail is not particularly steep or rocky, it is bumpy and includes short stretches of steep side hilling, with large drop-offs as well as half a dozen bridge like stunts for crossing over fences and creeks.   Trail can be ridden in either direction to mix things up.
