Have hammer ...

If you have an hour or so to spare and want to experience what it was like in the "good old days" when radio ruled the earth, go online and secure a copy of Escape's Earth Abides - a dramatization of George R. Stewart's novel about post-apocalyptic Earth. The hero of the narrative is Isherwood, an ecologist, and he and others he joins with along the way forge a way to the future with Ish's hammer as their guide.
