After you're done exploring the Alamo, checking out River Walk and taking in a show at the Majestic, now it's time to really get down and dirty in San Antonio to see things that most tourists might not know about. For example, what about the Toilet Seat Art Museum? Perhaps those who don't find toilet art to be high class entertainment might want to skip this one, but it's definitely something to tell your friends about back home. Located in the garage of a retired plumber (what, you were expecting a professor or scientist to be behind this musuem?), admission is free and the "museum" is open whenever Barney Smith (the owner) is home. www.unusualmuseums.org/toilet

On summer evenings around dusk, go to the newly opened northern section of the riverwalk, just downstream from the San Antonio Museum of Art to see the lights come on inside the giant sunfish public art installation under IH 35, then wait for the growing bat colony housed in the bridge's structure to emerge.

The San Antonio Cultural Arts Mural Tour is another one for tourists in-the-know to experience. The tour shows murals created by locals on the westside and takes visitors through the neighborhoods to learn about the murals and artists. For information on the mural tours, directions, or to set up a pickup time (the tours are by appointment only) contact Manuel Castillo at 210/226-7466 or mcastillo@sananto.org
