The Adventure Pass policies have changed to a small degree. In the past there was a boundary known as the recreational fee use required boundary. Signs are still in place where those boundaries exist. However, new enforcement has since changed, not having anything to do with the National Monument status. The Adventure Pass is required in all no host campsites, day use picnic locations, parking lots with either pit toilets, picnic benches, fire pits, elevated fire pits, and trash cans. They are no longer required by simply being in the boundary perimeter. If your not sure, it's best to hang it or place it on the dash. They have not been or will be required in host campsites such as Table Mtn. Mountain Oak and Jackson Campgrounds just to name the few in our area (area 38). Daily Adventure passes are still for sale in the usual locations in town and year passes may be purchased on line or at Grassy Hollow Visitor Center. Big Pines information center will be open when the position is filled. Senior passes can not be purchased on line as proof of age is required. Basically were ever there is USFS improvements such as mentioned above they are still required and will be enforced. No word yet (that's been passed to me) on the future of the Adventure Pass or any such fees since the National Monument signing.
Hope this answers your question.
