Wyoming as a whole does not have section line row established or unestablished roads/trails for public access, atleast the areas I surveyed up there around Gillette/powder river basin. You may have access to blm,usda, section section 16 (school) or private owners land but unless you get permission from other owners to access that land via private roads you are not legally able to hunt that land you have permission to hunt. Also the company I worked for who was surveying for Enron Oil and Gas (EOG), EOG actually had to buy access to these sections we were surveying by providing the needed information as to how many people and vehicles we would be using on this privately owned road.
