IIRC, concrete is ~$90 a yard, and there is 40 yards in that slab. It's 5.5" thk with 1-2' deep perimeter footings, and 1/2" rebar on 1' centers.
That isn't the finish color, it's going to be acid washed when it dries so it will be a bit lighter in color.
There is a 8' wide horse trail in front of our house, and another behind our house. All of Norco has horse trails and equestrian parks. At one time, there were more horses in Norco than people. Many stores have hitching posts and water troughs. I don't have horses anymore, but used to have two horses years ago, an Arabian mare and a Quarterhorse gelding.
