The map has been changed slightly to show a multi-colored ghost line of the various routes. The East coast leg is green to represent spring; the Northern leg is orange to represent summer in Canada and the Great Lakes areas; the Inland Rivers leg is brown to represent fall. The barcode that was in the lower right hand corner on earlier maps has been moved to the back. If you have one of these earlier editions, the barcode can be covered up with your boat card prior to framing. 22" x 26" laminated.
