We are driving in from New Hampshire and don't want to take our car into the city. Is there any place we can park our car and then take the subway into town?

The Alewife Station at the end of the Red Line next to Route 2 in Cambridge has a parking garage; they charge $4.00 a day. However, if you're coming on a weekday, be aware that the garage fills up with commuter's cars by about 9:00 AM; I think some spaces start becoming available by early to mid afternoon. Weekends are better, but it will fill up for special events or Red Sox games.

It might be easier for you to drive to Lowell, MA and take the commuter rail to North Station. In the alternative, you can drive to Nashua and take the bus to South Station. I believe that the busline is Vermont Trailways (Greyhound).

As Sara indicated with Alewife Station is also true with most other MBTA commuter lots - Oak Grove, Sullivan Square, Wellington (all on orange line) fill up well before 9 AM - some by 7:30-8:00, or a little later in the summer. You might also consider Trombly bus lines - they run mostly commuter runs from Merrimack Valley (north of Boston) and many lines have little, sometimes free, lots at various stops along the way.

There's a Logan Express that runs from Framingham. I don't know about the North Shore.
LE is operated by Fox Tours in Milbury MA. Give them a call. They'll know.

There's also Logan Express in Peabody and Woburn. Problem is -- it goes to Logan! Also, the cost adds up: parking at the Logan Express lots is about $8 per day plus the RT fare is about $15 per person.

There is a Logan Express in Peobody and I believe there is one in Woburn as well.
