In addition, he rode some of the sections which we hadn't quite worked out the correct route, namely the section between St. Anthony and Dubois. As a result of this second trip into the sand dunes north of St. Anthony we have figured out a simpler route (with fewer gates to open and close) to Dubois.
Brandon said the route was incredibly beautiful and very isolated. There are very long stretches between towns and resupply points. While there are streams along the route, many have active cattle grazing, so be prepared either with lots of water or a water purification filter system you trust to handle streams with cows in them. And smaller towns like Jackson, Montana have quite limited services and stores. You'll need to plan appropriately.
