I used to live in Tacoma, and ride my motorcycle across that bridge frequently..even though the bridge is strong now, it is still a hairy ride. The winds are so strong, I would find myself leaning 30 degres into the wind the whole way across, trying to keep a straight track. It was a great skill exercise!

Interesting video, but it bears no relation to crop circles on Earth. Many of them involve complex, detailed, and precise geometric designs without any errors. To say they were created by natural phenomenon is like saying that Da Vinci painted the Mona Lisa when he accidently tipped over a can of paint.

Really, it's worth looking at some images of crop circles..whether they are of terrestrial or extra-terrestrial origin, they are some stunning, amazing art.
