What's in your backpack?

We all know that CapitalOne saying "What's in your wallet?", right?  Well, I know a different saying; what's in your backpack?  As we are leaving on Saturday, it is necessary to know what is in my backpack!  Currently, (it will change before we leave!) in my backpack I have...:

• My iPod Shuffle and it's charger; what would we do with out music?
• The Dark is Rising; for school...
• My "once" lost sketchpad; it was an honest mistake!
• 6 freshly sharpened pencils; for my sketchpad.
• A dog book or 2; -scratch-scratch-

So, this is it -for now-!  I shall return!
