My wife suprised me with a gift last night (no it's not what you probably were thinking of), she gave me a T shirt with the 3 Stooges riding vintages bikes and the logo says "Knucklehead Riding Club" I know that our beloved SOHC bikes are not knuckleheads but I'm pretty sure I am one. I attached a picture, it's not very good but you hopefully will "get the picture"
What a great shirt.
