There was once back in the 10th century seafaring fellow who lived in Norway. He had a bad temper..he killed a
neighbor. It was pure temper..so he was banished from Norway.
So Thorvald had to go somewhere! At that point, little choice..so he fled to Iceland..
..But wouldn't you know...his son's temper got brought on trouble once more.... So Erik the Red killed his
neighhbor...so here comes another banishment... from Iceland.
Well, not many options left...but he had. heard of this place to the north west, that some of his acquaintances
had come upon..so again Erik sailed west with a party and settled in Greenland.
It sounds like both Iceland and Greenland were 2nd and 3rd choices for that explorer.
