I showed up at 3:30 am and was about 18th spot? the line up grew to a few hundred people.
Granted I wanted to score my deals, and was a bit excessive in what I bought. If you're going spending a significant amount of money you have to decide whether to line up or not, they don't sell out but Ammo goes quick. If you have your eyes on a gun the prices don't usually get better than November / Dec
