Frontier strategies

       Not all who wander are lost.

Depending on your lot in life, you have to variously protect yourself from migrants or from rattlesnakes or from dehydration or the border patrol.  Different strategies are employed - 45's loaded with snake shot, bottled water dropped at various locations; walking thru the rugged "desert" to avoid detection, erecting high border walls.  See these illustrated in my Flickr set.
