All the toilets are closed and I assume as are the Visitor Centers. The Park Rangers will also not respond to any emergencies. You will have to call 911 and get State or Town help.
But, they have NOT closed the gates! That is good — but that can change.
An irony of such Shutdowns is that they STOP updating Government Websites! So, you can’t find the latest status of Park closing on the Web. They will not be answering the phone either.
But, for now, this is better than what happened during the 2013 Shutdown when they did close the gates pretty early on.
I will try to keep you posted.
