I'm Chinese so I want to say China- there's soooooo much I have to see there, and I've got to see it before pollution ruins everything.=____= And then there's Germany and the Sanssouci Palace. Japan would be nice too I guess
In the end though, I think it's Switzerland I absolutely must, must MUST visit.
And I lol'ed at your APH comments...it is true, APH takes over your life, don't get sucked in! *coughlikemecough*
