OK. I'm guessing you might be at Boston Minuteman Campground. If so take left out of the campground and when you come to the rotary, take the exit for Route 2. Take 2 west to 190. Follow 190 to 290 to the Pike west. You are now only one exit from 84 - no matter what you are driving, toll will be under $2.00, probably closer to $1.00. Trust me, you don't want to deal with alternatives. We live right off the 290/Mass Pike exit. If you are not at Minuteman, just find route 2 and go west to 190.
