For those of us who can't fold for shit: Crumple Maps

My one question/concern about these maps is whether you can write on them with a pen or pencil. I like circling my hotel and the places I want to see on my map, and it can be fun to look at that again later or lend a marked-up map to someone else visiting a city.
