We first saw Andrew Goldsworthy’s stone sculptures at Storm King Art Center so it was a marvelous moment of serendipity when we found two of his pieces on the woodland sculpture trail from the Frank Lloyd Wright home at Kentuck Knob back to the visitor center. 
Both pieces were large and slightly mysterious.
If you want to experience serendipity go small and get off the tourist track.
