People at Moltnomah Falls

Everytime I go to Portland for work I find myself going to the falls in the gorge. I've never been able to get these fall to myself so I decided to try to show the people at the falls and choose to take a 30 second exposure to show people coming and going. At first look I though the woman in the blue coat to the right of the falls that never moved for the whole 30 seconds messed up the shoot. But when I looked again she makes the shoot by just staring at the falls without moving for over 30 seconds.
