Wandering Backpack: Calvin Laituri
Camera: I need to take pictures of things I come across.
Pocket watch: I need to tell the time somehow.
GPS and compass: How else would I know where I am and where I’ve been?
Pocket knife: It’s useful.
6×6 Rubik’s cube: You can entertain yourself for hours with it.
Notebook: I would bring a notebook to draw anything interesting that I find.
