Well, as Shykre says, if you're up at all the wrong hours and speak Japanese, you can always stop by Bastok Markets just left of the AH. We start meeting up at 3:30AM PST Sunday mornings and generally head out around 4:00AM.
Just checked Roukii's link and found out that's me!
(Well, I'm small tag-a-long part of the BastokanTempest contingent that goes on these).
