vaguely related, slightly OT: rode to work today, I'd wondered who belongs to the matching baby-blue cruisers I see locked at the BART station. So today I found out.

As I was heading for the elevator the young couple rode up, they seem cheery and happy to be riding to BART on cute matching cruisers with their helmets securely on tight...backwards!!

I smiled, waved, pointed at my helmet, said "your helmet, it's on backwards". My smile was returned but I'm not sure they understood English, hope the visual (point, motions turn hat around) was enough.
