I've been busy. Had to uncover my septic tank, which is two feet down. It's been emptied, and now I'm going to build a stacked 4x4 pressure treated 'riser' which is a box to cover my three lids. It's going to be a lot more work, but it should last a long time. It will have a three quarter inch pressure treated top which I will put planters on. I never want to have to dig that much dirt again. Cost me $450 for the septic guy, and $500 for the lumber. And... it's raining, so I have a tarp full of water.
