Jack, I've seen that sign before.... it could apply to all the mile tracks, the bub, the street bikers that get a photo of their GPS....
I often get told by folks that they owned a Bonneville 20 years ago, or their dad had one... one lady told me she had an old Bonneville bike in the garage... tried to buy it, but she was keeping it for her grandkids.
Then there are the guys that say how fast did you go.... those I usually spend more time talking about the club. Most don't realize there are classes that you need to go well over 400 to get in the club... I usually explain all you usually have to do is go faster than anyone in your class since 1953....
