The Japan Current has been bring us stuff for centuries. The high prizes are the hand-blown glass fishing net floats,
many of which are still in their own little hand-woven net coverings. I've seen them in collections = from grapefruit to basketball in size.

This time around, the crud should be here soon, from Oregon north to Alaska. So far, the best of the best was a 15-20m chunk of boat dock and a big motorcycle, packed in leaky styrofoam. Electrolysis in seawater kind of tarnished the "crotch-rocket." The original owner was found, the guy said he didn't need it back.

The real concern is what's maybe coming as "hot stuff" from the Fukishima (sp?) reactor itself.
I suppose if we stay up really late at night, we will see it coming.
