I'm actually living in Millis now so I'll take 109 out to 495 (Milford). 109 is kind of congested but I can also take 126 to 495 as well which is just one exit south on 495.
On your way up 495, if you get off at exit 18, Bellingham Rt 126, and bear right at the end of the ramp and take an immediate right at the next traffic light, there is a Pier 1 Imports store that usually has an empty parking lot. I can meet you guys there if you want. That way you can't miss me and its less than 30 seconds off the highway.
