Calvin Trillin, Runestruck (Little, Brown, 1977).
When two gas station attendants find what appears to be a Viking runestone while clamming, a (fictional) small Maine town goes agog with Viking enthusiasm. Berryville is set to lay claim to be the site of America’s first Nordic colonists, although there are some skeptics, too. A comic novel, including some fine faux country-music lyrics.
Little about Runestruck on the web, but there is much Trilliniana. Here is Wikipedia’s entry about Calvin Trillin. Sue Russell wrote this entry about him for the St. James Encyclopedia of Pop Culture. Dave Weich interviewed Trillin for Powells. Here is an appearance on Charlie Rose.
