I don't know if I could ever completely give up my truck as I love camping and hiking (and some places are just too far away to ride to within the confines of a full time job), but my wife and I moved to a town just outside of Philadelphia a few years ago that has a train station (for the railroad I work for) so I do go weeks at a time without driving. It's such a great feeling to get to work, run errands, etc. under my own power and I don't see that changing anytime soon. One day I'd love to be car free, but car light seems to be just the ticket at the present time.
