No I did not know that, Other Tink.
Here is my (quickly taken) interpretation: We in the 21st century are accustomed to going about in autos, airplanes. But historically people traveled about much further than we would expect to be commonplace, and took the discomfort and deprivations as part of the adventure. For example, the county fairs that are so popular in America (Europe too), they have apparently been going on for thousands, even tens of thousands of years...so a Viking travels to a fair in Spain, and meets a ladylove from Italy or something! (Would have kept the genetic pool diverse and strong.)
When I lived on Mt. Baker in Washington State, I learned that wool from mountain goats there has been found in blankets as far away as the East Coast!
