Liquids are in the TSA standard 3-1-1 fashion in the top-front pocket where they are easily reachable at the security checkpoint. Earplugs and neck pillow are in the top-rear pocket along with two iPods, two sets of headphones and the Apple airplane power adapter.
The amount of things I am taking is pretty slim. Other than my camera and computer, I only have toiletries, one pair of pants, one pair of shorts, a few pairs of underwear, and a few books. The backpack I selected has plenty of room. I still have to iron out the details of keeping things organized, but that'll come with time.
Right now I'm just really tired... I need a good night's sleep. I'll write more about the last few days once I'm on the plane to Tokyo, but now it's time to enjoy the last bit of good sleep I'll probably get for a few days.
