I am 75 miles from my office and have a few options, but one I do regularly. I drive to the train station or ride to the express bus station which takes me and the bike to the train station. Then the train the city with the office. I can catch our campus shuttle there or ride my bike the 6 miles to the office. It changed my work routine quite a bit as I used to stay late all the time to avoid the worst of the traffic on the way home but now traffic is not an issue on teh train.
