During the 2013 shutdown, no federally managed lands were closed off to the public...at least not around here. I never heard any rumors that they would be either...except maybe the parks, which are supposed to remain open this time. I am sure there'll be all kinds of off roading in the WSAs and wilderness areas with no law enforcement, but oh well. I think some of the campground facilities were locked in 2013 (since no one was available to maintain them, such as pit $hitters, etc.) but that was it.

I killed a bull elk on US Forest Service land during that shutdown...there certainty was not any signs or radio announcements saying I shouldn't have been there.
