I was just thinking about those tokidoki bags!
Now is that one for over the shoulder, or like a fanny pack?
I like the little fannypack ones that they have, but I'm not too sure if they are big enough to carry around the parks..?
I carried around a little jansport (mini) backpack last year and it seemed to be the perfect size for 2 bottles of water, my wallet, my camera, maps, and a few other little things.
