Puh-lease, Rye. I'm going to pack for a 7 months trip, and it all has to fit in a backpack that can contain 60-70 Liters :P But then again, I'm not actually moving to another place, just travelling around and stuff..
But you're like, backpacking through Europe from hostel to hostel! That's different!
Not Europe, but Asia and the US. Even coming to New York
