Once upon a time, there was a family that lived on a piece of land that was very sloped and very full of rocks. The family noticed that every time it rained, water was directed right at their home, and every time it iced or snowed, they couldn't walk up the slippery slope and into the woods in their backyard. So they decided to rent a little skid-steer and do something about it.
First, they cut away the earth so there was a level place between their home and the beginning of the slope. They piled the dirt high as they dug away. The kids squealed with glee at the mounds they could now climb, and the Mama did mounds and mounds of sandy laundry.
Next, they gathered all the boulders from their land and took note of the ones that were too small, the ones that were too round, and the ones that were juuuuuuust right.
Then they called for help from the finest helpers in all the land, and the family began to build a wall.
There is still much work to be done around this new wall, but the hardest part is now finished thanks to the weather holding, the helpers that came and worked, and the little skid-steer that the Daddy drove like a pro.
