We first saw these sculptures when we were driving somewhere downtown. It's a clear view from the street when you're stopped at a traffic light, and seemed like something that was very "Texas" to a first-time visitor.
Later, we encountered them up close on the free Public ArtWalk, and were even more impressed. Each of the cattle are bigger than real life and have great detail. The sense of motion using the geography is really well done, as is the incorporation of water into the display.
This is a cool thing to visit if you like art, and I can imagine kids would absolutely love it.
