From Mitchell, SD head north on Rt 37, turn right to head east on 243rd St (dirt road), down the hill into a gorgeous valley, across the bridge over the James River, back up the hill out of the valley, then turn left to head north on 412th Ave (dirt road). You’ll see the colony's silos from the corner of 243rd and 412th. There is a big TrailManor Industries sign with the orange and brown logo on (I think) the left hand side of the road.
