progress report - have to complete the shed, the drainage, the clothes line path, the path to the shed and then the area near the observatory before i can do the observatory. that is the order dictated by SWMBO. she also doesn't like the backyard being a mess.
So i have buried a keepsake - the ugly birdbath that was in the backyard - sort of a talking point - the body under the slab
so have dug the path (thanks for the help Scott) and the drainage and the rubble pit are now done
