JJROB2: I did go to the cave today. At first it appeared that they had just blocked the road a mile before the cave, however, I walked to the cave and there is a large metal grate covering the entrance. It appears to be permanent. On my way back into town I stopped and talked to a USFS law enforcement officer. He told me he suspects the grate is permanent, however, it was originally placed there because of people entering during closure. He is going to contact his superiours and ask about this.
