Welcome back to the Dakota Rail Trail! This section seems to be sorely lacking in caches, so I got creative. Here's something to get you outdoors. At the posted location you will find a rock. It's pretty good sized. More like a boulder. You are going to project a waypoint from this boulder. How far, you ask? What direction? Well, that is for you to figure out. What color is the boulder?
Blue- Distance 210 feet
Bearing 90°
White- Distance 153 feet
