Now and again, we see something new on the Sudbury River. Today, a single boat towing 7 canoes passed by the house heading downstream. My guess is that is has something to do with the water chestnut eradication project that has been underway for several weeks. Our neighbor and friend, Dave Witherbee, was skippering the tow boat, and I will ask him about this the next time I see him. I am curious to know how one stops such a flotilla without creating a pileup. I suspect you have to do so very slowly.
