Days, sometimes long, are passed doodling memories, much like being there making a sketch, and reliving moments long gone. No better way to pass the time than to let your mind wander, and paddle up a channel on a northern lake that you promised you'd revisit one day, but never had the time.
It's meditation of a sort, doodling. There's no pressure to get it right, just push the pencil here and there, scribble a line, and make it come alive....if only in your mind.
