At Washita Mr. Crayola tried to make a map, even if it was merely a suggestion on the direction to go.
Thats because the owners had nothing to do with making the map. The local Jeep club made the map and most of the trails. They do nothing to keep people on the trails and they don't get maintained. When an obstacle gets too hard the dumb Jeep guys just make another trail around it.
What do you expect from a Jeep owner?
