I saw the Gateway Arch when I was a kid (called the St. Louis Arch at the time? Or maybe that was just what we called it), and it's been probably 20 years since then. It's definitely impressive, although I wish the grounds were bigger and had a little more separate from the city.
Obviously it's been photographed about a billion times, so I tried to get something unique that gave it a sense of size. Not sure if I succeeded, but I do like how this shot turned out. There are a couple people walking through the frame in the lower right which really makes the arch look massive.
