Living the dream, bike commuter-wise. My boss is super green, and we are all encouraged to bike/walk/public transit. We're not allowed to drive, actually! We can keep our bikes pretty much anywhere in the office, and have stocked showers with toiletries and towels and all. It's a great set up. Many others in the office ride, so it's very bike friendly.

Only "problem" is that I'm only about a 10 minute bike ride from work, which doesn't result in all the much exercise, so I switch off between riding and walking. Maybe I just need to extend my route...
