If you want, or if Lisa encourages you, you can walk across a bridge that is 955 feet high, 955 feet of air below you. If your hat were to blow off, or if you dropped your book of Chaucer poems, it would take about nine seconds to get to the land below. This is a very long time to fall. If it were you who were dropped over the side, you would be moving at 110 miles per hour when you reach bottom. I recommend against this.
