Sang I was in St. Louis about three months ago . A visit to the incredible ARCH by the river is a must. It was built over twenty years ago & is a real wonder with the stainless steel monument ( in perfect angles) meeting at the peak There is an elevator inside which pauses as it moves in a circular manner. The engineers who designed this structure did a good job. The scenery is even better at night on the Illinois side not the Missouri State section. Have a safe trip. Habib
