it'd be a fantastic way for visitors coming off the train to run errands in new haven that would require a car, a really convenient place for residents to pick up and drop off a vehicle, and a great way to spread the word about zipcar.

Solid, this might happen soon.

Apparently, T&P has been working on this for over a year.

That's great - was glad to see the article. We need Zipcars citywide. I love using them, but probably wouldn't if they were located more than a few blocks from my house.

There are Zipcars at Union Station now.
