Sign spinning is a southern California export not seen very often here in Tennessee. I saw this spinner working outside a Great Clips barbershop on busy Harding Place near Belle Meade in west Nashville, and he was very good indeed! I didn't have a video cam but was able to get a few stills before he went inside for a break. I wonder if they're union? :-)

I found a good video of a SoCal spinner at http://www.aarrowads.com - seems to be a real art form!
