The sod I put down on the two bare spots, from where Emilie's swing-set sat, is doing terrific. Nice deep dark green. It's liking and responding to the nightly hand watering it's receiving. I'll also give myself a pat on the back for the prep I did before installing, which was to turn the soil with a shovel, mixing in some rich chicken and rabbit infused compost!
Now if we could get a good soaking from Mother Nature the rest of the lawn might green up some so there's not as much of a contrast.
