How to attach a monkey-bar/playground structure to the ground in my backyard?
I put tie-downs in my driveway to guy down my boat canopy during the summer. I dug 2 foot holes, crisscrossed rebar diagonally into the ground, poured concrete, and sunk heavy duty eye-bolts with alternating nuts and washers into the concrete. I will be doing something similar this summer with posts, sinking them into concrete, with rebar through them.
