==Mysterious runestone== 

 Wiglaf, a belated reply to your comment on the Kensinggton runestone: Does it not seem unlikely that some old farmer in northern Minnesota (which is not good farming country) would be erudite enough to carve runes that would appear to at least some knowledgeable people to be authentic or possibly authentic? Understand, it doesn't matter to me whether the Vikings reached Minn. or not  I just think it's an interesting puzzle.
