What seemed like a lot of bricks at the time now appears woefully insufficient.  I may dig out the clay and fill in the nice garden soil more or less to ground level and call it good.  Now I just need to figure out what to do with all the old dirt.  I do have one low spot in the yard I guess I can level out and replant the grass on.  The clay I dunno.  It's pure orange clay a couple inches below the sod.  Does anyone like pottery?
