Amazing!!! Our backyard needed to have some drainage pipes put in and in order to do so, they had to break up the cement and send the down spouts into the ground and connect them to the pipes. When they put the cement back, we wrote our names in it. It was a lot of fun!! Cement is difficult to write in! (You can see Smiley's feet in the photo--he needed to see what I was doing with the camera. And he was NOT happy that we did not put 'Buzz, the Kitty's' name in the cement.)
