This Land is Your Land

While camping on the North Shore of Lake Superior this week, we went for a hike down Beaver River. Walking down the river to the shore of Lake Superior, we came upon a sign that reminded me of a verse of Guthrie's song This Land is Your Land:

This land was made for you and me.

As I was walking, now they tried to stop me.
They put up a sign that said private property.
On the back side, it didn't say nothing.
So it must be that sign was made for you and me.
