sandbox building

Here my Dad(Nate) and me are upgrading the sandbox to 4.0! I know much of you are wondering how we do this, well, the steps are: 1.make the floor of sand flat 2.put in the leveling sand 3.flatten the leveling sand 4.even up the amount of sand everywhere in the whole area 4.get familiar with how the blocks fit together 5.look at them and find out how to fit them together 6.put the blocks together like a puzzle. In the picture I am trying to lift a large block puzzle piece! My dad is smiling!
