Prep the back yard for hammock haven construction

I'm building a hammock haven to enjoy this summer. Anyone who helps prep for it or who participates in building it during the VBC May 25th -30th is welcome to come swing in the hammocks or camp out for a night! We will be digging up the back yard, and leveling the ground then putting down fabric to keep the weeds from coming back so profusely, then digging and setting the posts. Lots to do and your help is greatly appreciated.
