[quote=Gelcube;7237]You know, I can’t help but wonder if some vikings managed to make it down to the American South. In a lot of ways they bear a striking resemblance to the Southern American group called “redneck”. They love their gods and weapons, and a lot of their adventures start with “Here, hold my beer and watch this”.[/quote]
Hmm, that quote is the deciding piece of evidence. Clearly they must have.
They did trade with Persia via the vulga trade route, and eventually to Italy by going around the coast of Spain. They also traded, at least indirectly, with China. Not to mention upper North America, could very possibly got down there and established a lost colony.
