Go buy that wood canoe, too! :D:D:D

That is excellent answer... don't know if right yet but can check it out... understand previous owner did own canoe as well as I heard his estate selling one--a 1950's wooden canoe in excellent shape, they say. Thanks for your reply as well to everyone participating.. it was fun!
