There is a Seasonal Store just about 1 mile south of the stadium, on the north side of Rt. 1, at the junction of Rt. 140 and Rt. 1 - 113 Washington St. in Foxboro. I park there when I want to get out quickly, I can turn on rt 140 and head to Walpole, missing all the Rt. 1 traffic; you could jump on 140 and head south, which would be convenient for you. If you can get a spot there you should be pretty good. If you are not parking at Gilette proper, find a lot south of the stadium, that way you do not have to crossover Rt. 1 traffic when you leave.
