While the above info on the train and subway are cheaper and with more options, ($2+$7+/-) this option may work if I am able to pick people up on the way down....
One could also forgo the subway and train thing and if coming from BOS Logan Airport, consider this:

http://www.massport.com/massport/gtu...es/Woburn.aspx
The second link above says:
Leaving Logan to Woburn
Weekdays 6:30 a.m. - Midnight every half hour
Adult One-Way Fare: $12.00
Adult Round Trip Fare: $22.00
More information about Logan Express is available twenty-four hours, 1-800-23-LOGAN
The trip should be about 30-40 mins and would be against rush hour traffic for the most part if coming into Woburn from the city in the am on a weekday.
I am not sure if this could be of use, but perhaps this would take you from Woburn to Lexington, which is near the courthouse (and Cartera):
