I recently visited Trinity University in San Antonio, Texas with my daughter who is a senior in high school. In the center of the campus, stands this beautiful tower, a conglomeration of bricks and metal which come together to produce a sense of both lightness and strength. It seemed the perfect symbol of the students' power to stretch themselves and to reach for great things. Under the old adage that the best camera is the one you have with you, I shot this with my iPhone 4.
