I transferred work places and had to introduce our office to bicycle commuting. The first few months people in the office were A$$holes including upper management. I stuck to my guns and no one cares anymore. Interesting, there are now 6-9 bicycle commuters a day when I started there were nil, zero, zilch. They are remodeling our office spaces and they will be installing a shower and changing room along with enclosed outdoor bike rack. Encourage others to bicycle commute once a week or once a month and before you know it, you are just part of the crowd.
