The wife and I promised our 3 year old a swing set for her b-day. The only DIY was prepping the ground and leveling it for the install. Let me tell you...that was plenty. The area measured 29'x26' (754 sq. ft) which was tilled, dug 4 inches down and hand wheeled into the dump truck. 1 night measuring, marking and tilling. 3 long nights digging and a final night tilling and then leveling. We were smart and paid for the install. They installed today and were finished just under 5 hours.
