In the 10 or so counties that I routinely drive through there are ZERO bookstores. No indies, no bog box, NONE. Each county has at least one WalMart, and there are magazine racks and paperbacks in the grocery stores, but zero book stores.
Amazon did not kill the bookstore, nor did B&N. An apathetic non-reading public killed the bookstore. They can only exist in major cities where people like us, who read, live.
