I'm wondering how the whole situation is like as this will be my first camp out - pre-order for an apple event. For both pre-orders and for camping out in the past. Tips from people that have camped out for previous apple products? How quick do pre-orders run out that people go to the stores? And even then, are pre-orders directly from an apple warehouse and not a local apple store? Questions, questions, questions! Thank you for any responses!
