I like to bike and hike in the nearby Indiana Dunes National Lakeshore park which is about 15 miles across covering Porter and Lake Counties in Indiana. There are multiple parking areas throughout it and everytime we have one of these government shutdowns, the first thing the Feds do is close off all the parking lots which makes it a real hassle to go there. Since the park encompasses highways, roads and beaches you can go there but you just can't park there or use any restrooms which remain locked up. I usually park in a public place outside the boundary and go in. As for MDing there that's never allowed so no effect on that.
