Rock Concert: Dick De's creation even fooled his contractor.
'Rock' Your World (Or At Least Your Backyard)
By Gizmo Guy Dick DeBartolo
“It is a faux rock that actually fooled my contractor until he tapped on the "stones" and discovered they were hollow. Each section is about 42 inches long and they dovetail so you can build all sorts of creative designs in just minutes. I used just eight Rock Lock sections but it really turned my backyard into something special.”
