One theory about how Santa gets all his work done is: Coffee. Lots of it.
Even if you're not St. Nick, if you need to stay alert driving on Christmas night, the state's highway service areas are here to help.
All 18 Department of Transportation service plazas will serve up free java from 10 p.m. on Dec. 25 to 5 a.m. on Dec. 26, including Westborough westbound on the MassPike.
The same offer applies between 10 p.m. on Dec. 31 and 5 a.m. on Jan. 1.
The free coffee is sponsored by McDonalds, Burger King and Gulf.
