As an overnight cashier at Wal-Mart, I can only say that people in small town Kansas are not that abd. What did Wal-Mart have that was worth rushing the doors for? Well, our store is open all night so we didn’t have a sudden rush at the doors.
Perhaps, but more likely there just aren't as many people. Huge crowds are dangerous by definition. It only takes one person to do something stupid and set off a panic, and a huge panicked crowd is unable to organize to act rationally.
