When the Walkers reach the 115-mile mark at the beginning of Chapter 9, what locations do they still have ahead of them and in what direction are they headed?

As they walk south, Garraty estimates that they are forty-five miles from Oldtown, 125 miles from the state capital of Augusta, and at least 150 miles to Freeport. The word is that they walk will go at least as far as New Hampshire, which is 230 miles away.
