Funny sign and, oh, how true! I went to a BMW national rally a few years back. After the closing ceremony, about a thousand Beemers fired up at the same time. I didn't even have to raise my voice to talk to my passenger. (Though I almost got blinded by the modulated headlights and reflective riding gear.)
Compare that to Main Street Daytona or the Weirs at Laconia. I know this means something, but I'm not sure what......
