Goonie is a legit stroke. THE stroke for straight line river travel.I pretty much picked it up on my own as a young lad during my summers at a friend's place in Cobden, Ontario. ("young lad" is a term that always brings me back to those wonderful summers of my youth back then in Cobden)
I guess the goon stroke was my go-to stroke, later in life I picked up a book or magazine and learned to paddle somewhat better. I never had any formal instruction, no doubt I would have benefitted from it.
