Or they could have stuck close to land on cloudy days...like they did on most days (sunny or cloudy)

Wonder if I could use the same technique with my polarized sunglasses? (I tend to completely lose my sense of direction on cloudy days. Especially in the Dallas suburbs, where streets are NOT laid out in a grid and tend to run every which way.)

Now that is really, really cool.

Here I thought crystals were just for wishful thinking. "For centuries, crystals and other gems have been desired for their alleged magical healing and mystical paranormal powers. This belief continues today among occultists and New Age healers, even though it is based on nothing more than testimonials, the placebo effect, selective thinking, wishful thinking, the Forer effect, sympathetic magic, and communal reinforcement. There is no scientific evidence that crystals are conduits of magical energies useful for healing and protection, or for telling the future."

Did you see this. Unrelated I know but still pretty interesting:

: "An ancient silver coin found in building remains in southern Athens is seen in this undated handout picture provided by the Greek Culture Ministry on Friday, March 2, 2007. Archaeologists have discovered extensive remains of what is believed to be an ancient marketplace with shops and a religious center at the southern edge of Athens. The finds, in the coastal neighborhood of Voula, cover an area of 1,500 square meters (16,000 sq. feet) and date from the 4th or 5th century B.C. the Culture Ministry said Friday."

I think they found a sunstone in a recent Viking grave. Can’t remember the source though.
