Cline has described Foamhenge as his greatest achievement.  He has additionally built hundreds of dinosaur statues, including thirty for his own Dinosaur Kingdom and nineteen for Dinosaur Land (Virginia) in White Post, Virginia, the park that inspired him to sculpt.  Cline's work appears in attractions across Virginia, including a concentration of works in and around Natural Bridge, where he works out of Enchanted Castle Studios. His studio appears in the book Weird Virginia and the Roadside America books and website. 
In 2001, a fire destroyed much of Cline's studio.
