As noted in this space before, Raiders fans are into tattoos. And that's pretty cool. Like a snake shaking its rattle to warm others to stay away, Raiders-themed body art allows common folk to distinguish between the innocuous Raiders fans, and those who are barreling towards their third strike.
SI.com recently ran a feature of sports fans and their tattoos. Not surprisingly, nearly a third of these fans pictured are Raiders fans. Although Bears fans are starting to catch up.
