I work nights so I'll be sleeping most of the day... I wonder what time I should set my alarm for and head to BB for a chance at getting an ipad? I dont live in a huge city, around 150k. 

Well if BB is your only option be prepared to wait and or get lucky. It seems from all the threads tonight that BB, Target, Wal Mart aren't really getting a huge shipment. If you really think about it, it makes sense. Apple wants to keep lines pretty big at their store. They're fine with selling it else where but they won't provide those stores with over whelming stock.
So to really answer your question I would say try to get there at 12 or 1.
About 3pm. Probably to NOHO Broadway store in New York City, I have a work related appointment nearby, and easy to get to Apple Store in case of a sellout.
Shooting for 32gb black.
