Not sure how much of this trip along the US-Canadian border will be by canoe but it starts out that way in Maine and must use one through the BW. From The NY Times, “Porter Fox is the author of “Northland: A 4,000-Mile Journey Along America’s Forgotten Border,” which will be published by Norton on July 3, and from which this article was adapted.”

looks like a good read. i've never been out east of Ohio so the eastern portion sounded similar to bwca paddling.

Thanks for sharing!
