And all these years I just thought it was a roll cast I was doing while flyfishing on the Eel River near Eureka - damn I wish I'd known I was doing asymtotic attenuation! I would have worn a Humboldt State hachimaki instead of my old fishing hat.
I'm selling those hachimaki for $25.00 each.
It has Japanese writing on it. Says "aikibodo".
Let me know if you want to buy some.
