A coworker was on the citizen board providing advice/oversight to our bus line, and he was working on getting the bus line to work w/ a zipcar style pool of cars to distribute cars around town (areas w/ enough potentially carless workers who could use them during the day). His intent was to get a deposit of cars here at our office, but it never came to pass. Still, seems like a sound idea.
That said, until the zipcars do turn up, we can check out company cars...
