It would have been utterly impractical given, as I recall, the distance was about 40 miles and would have involved a few portages around dams. (So probably more than 12 hours even at a pretty good clip.) But I live within about 1,000 feet of the (North Branch of the) Nashua River which joins the Merrimack River in Nashua NH and, for about 8 years, I had an office right in downtown Nashua.
