Located at Buffalo Bayou / Sesquicentennial Park, near the Smith Street Bridge.

This is an artwork by Dean Ruck; consisting of a motion sensor and a sound recording of a riverboat horn, downtown in Sesquicentennial Park.  As you approach the overlook pictured to the left, a recording of a steam, horn is blasted over a loud speaker.  The project is meant to fill in the audio component of the history of the site.
