I'm camping out in my bed, at home. Then I'm going out the next day and living my life normally, and not caring about the console. Then I'll laugh at all the idiots who thought they were going to score an easy $300 by going through the hassle of camping out some place only to come up empty handed because Sony can't meet demands.
That beind said, get to a Circuit City or Best Buy well before they close the night before... probably in the afternoon, check with a manager to see how many they are getting in and be certain that they are giving them away by spot in line, not random drawing. If they are doing a drawing, go elsewhere.
Hiring bums would be stupid. They'll split or mug your ass because they know (or think) you'll be carrying $700+. Or They'll leave the line when someone gives them a bottle of gin and $20 to get lost.
Sears might not even get but 1 or two, and who the hell knows which entrance to camp at most of them?
