If you're really committed to backyard fun, it may be time to build a sand volleyball court. Traditional outdoor volleyball courts are typically 60 feet by 30 feet (18.3 meters by 9.1 meters) -- although you can modify the size to suit your space. If you're not interested in hiring a contractor to install a drainage system, excavate a flat area and set permanent net poles in concrete, you could just opt to add the good stuff: sand.
After putting down a layer of gravel to aid drainage, top it with landscape fabric and two feet (0.7 meters) of beach-quality sand. The fabric will keep the sand from drifting downward, through the gravel, and into the soil below [source: Chavez]. Just think: you and your friends can reenact the iconic beach volleyball scene from the classic '80s movie, "Top Gun," whenever the mood strikes.
