What was the name of that FB page? Once the line is in full swing, you can leave the line here and there, but it is GA courtesy to not be gone for ages. If you check in tomorrow like we will there will most likely be a rollcall sometime Tuesday evening. The 6 AM rollcall on Wednesday morning is when you line up and pretty much stay in line. As I said, people come and go for a bit here and there during the day, but for the most part you hang out in line.
