I work at NPR in Wash DC, so we have a pretty sizeable (and mixed) population of hipster 20-somethings. Which is why I'm always so surprised that all I ever see storing or retrieving a bike in the bike room are guys like me in their late 30s, 40s and 50s. There must be 50+ bikes tossed in the storage room, but I only see the same couple of guys every morning.
