In summer the bikers frequently turn up downtown en masse. I'm not one of them (so far) but I enjoy their presence. I'm always struck by a contrast--I'm tempted to call it a paradox, but perhaps that says more about my own prejudices than about reality.
If you look at the bikers themselves, many of them exhibit what could charitably be called an easygoing attitude towards their personal appearance. I can't imagine they invest much time nor effort into it. And yet the bikes--they're spotless, meticulously polished--really beautiful. There's nothing in my own life that I put so much effort into maintaining in peak condition. I'm tempted to say it proves everyone has a sense of beauty.
(A second observation: I'm grateful to motorcycles for preserving a gleaming, chrome-heavy esthetic that went out of style with cars 40 years ago. )
