FYI: Shotgun hunting is being allowed in Round Valley through Saturday (to my understanding). The hunting is being limited to the lower/Camp areas around the reservoir. The Park Ranger there advised not riding any more than 3 miles southbound from the main entrance to the park. I believe this will take you to the sign designating the left-hand turn down to the camp area (I turned around before this point...). The trails to the north of there, going toward the boat launch parking lot, are unaffected. Of course, wearing orange would be an especially good precaution to take.
On a brighter note, despite the recent rain, as usual, the trails were in primo condition.
