I commute MWF from Northampton to Worcester via the Mass Pike, and can carpool from exits off the Pike. I leave the Northampton area between 7:30am and 8:30am arriving in Worcester between 9:00am and 10:00am. Mondays and Fridays I can leave Worcester any time after 2:30pm and don't mind waiting until 6pm; Wednesdays I get done between 5:00pm and 7:00pm.
We can alternate driving, or you can contribute $7 each way for gas and tolls. My car is no smoking, seatbelts required, sorry no service animals due to allergies.
