It doesn't take much to be a super star to your boy grands. Here is the recipe:
One flower bed---that has seen a better day--cleaned out down to the dirt
One roll of fabric bed liner--like used by landscapers
Few bags of sand
Bag of River Rocks
Bag of Gravel
Place the bed liner in the flower bed with really large rock anchoring the edges.
Place the sand---anyplace on the fabric
Place the rocks and gravel--anyplace on the fabric
Give boys tractors, trucks, and shovels--they will mix well and have TONS of FUN!
Recipe for a GREAT day and many more to come!
