I was too busy filming the checkpoint to take pictures of the men crowed behind the steel bars. These pictures don't show them rushing and shoving and holding onto the bars waiting to get through. But they do give you an idea of just how massive the line is. This is from the back. You'll notice that the line curves to the right alongside the wall where the barred-off narrow walkway begins. You can see the top of the walkway against the wall. This is between 4:30am and 5am.
