Thank you Jill and Shari. You gave me enough information about Bar Harbor and Halifax to plan now. I certainly hope we can see a good display of autumn leaves at the AcaiaNational Park on 10/12!
In Halifax, I think we will just take it easy and walk around the city. I saw somewhere talked about Fisherman's Cove near Halifax. It said it is a beautiful place but, from the pictures, it didn't seem to be too impressive. If you think otherwise, I'd be glad to hear your opinion.
