I love parkablogs, always a great source of information.
Indigo artpapers make wire bound (sketchbook style) Wiropads, which are excellent for traveling. The paper is fantastic, and can take quite a beating, scrubbing out and such; and the covers are good and solid.
Plus, because you can open the pad all the way flat, unlike a stitched bound watercolor pad, it's much easier to work on.
