I'm trying to convince my boss to convince his boss to enable me to commute to work by bike, it would be helpful if you could post some stories or pictures of silicon valley type companies with bikes somewhere (I remember seeing once the entrance to Facebook with a bunch of bicycles parked)

See the place where I started working is a tech company and they're trying (and in more than one way succeeding) to emulate that silicon valley start-up spirit (in eastern europe). They moved into a new building, with a gym, ping pong tables, olive trees, bright white furniture and large windows etc. but they really missed the bike commuting part of it, they have some reservations about it, so I'm trying to appeal to them with social proof, I imagine a bunch of people commute with bikes in those types of companies.

so, if you've got something, help a fellow cyclist out
