There is a property we drive by frequently and it looks like they might be dealing in huge stones. we see lots of stone piles on the property and a stone wall runs along both sides of it, (corner lot). too bad I can't get into their driveway to take a picture of a huge swimming pool with these type of stone fenced in. this picture doesn't do it justice, at it really looks quite impressive.
That is a very large stone wall and a lot of stones if they all came from their property!! This is the kind of work my son does. He's got all kinds of machines to help move the larger stones. Someone has done a very nice job here.
