Gary,
We will be ending in Brattleboro VT. The resteraunt is about 1/2 a mile from an on ramp to Rt 91. That is as close to Mt Carmel as you will be all day if you come along. Our closest point to the cape will be at about 9:30 in the morning.
The cruise itself is something like 240 miles.
Why not get a room it the Brattleboro area the take a relaxed cruise home the next day? Southern VT and the Berkshires are beautiful and have lots of nice twisty roads.
