Yep, that's me!I have seen concrete recreations as i have built a couple my self on some crazy projects to hide speakers etc a long time ago. The big thing in that process is to dye the concrete as you mix it the color will never go away but when you add it up to make a larger boulder with wire mesh and concrete time spent and overall appearance you dont save a lot. if you place some adds on local builtin boards at the coffee shop or talk to landscapers working in your area you never know in time some one may have a project close by and they might be able to help you out for pocket change especially where your pond i believe was right next to your driveway or do i have you confused with another recent build
