Yeah the DS is a necessity. Can't think of anything else tbh, my ipod... Maybe some manga?
I remember one guy, I can't remember who, brought about 30 of his manga or something? I remember when he put them up next to each other like you do on a bookshelf, they went from one end of the bed to the other.
But bringing manga doesn't hurt, you can read it and other's can read it, and, you know we've got to have a drawing session

DSW will know what I mean - 'cept there won't be a corridor to do it in XD
