My company installed lockers, showers, indoor bike rack, and a $50 gift certificate at then end of the month for alt transportation/car poolers. The first week, there were quite a few bikers. But only one of them finished out the month. He stopped at the end of August and it's just been me. Which is fine by me since it means I don't have to worry about people waiting for the shower. There are still a few car poolers though. No bus riders anymore after that first month even though there's a bus stop right at our front door.
