Norwegian salmon trader Bjorn Aspheim was only supposed to move to Spain for two years. Seventeen years later, he is still there.

"I think I was the first wild person that tried to do this, but I didn’t know what I knew today," Aspheim said wryly.

"If I had known what I know today, I would have done something more intelligent with my life."

The "this" is the building of Europe's largest indoor shrimp farm, Noray Seafood, 185 miles from the nearest coast in Medina del Campo, which is 100 miles northwest of Madrid.
