Thanks!

I called Home Depot and Dixie Rents and they both rent a small sod cutter.
My brother-in-law also has a tiller. Tiller would be free, sod cutter would be 80.00 for a day.

Now I'm worried about the cats. Someone posted that a cat popped their pool. We have "stray" cats that come out at night; they like to sit on our fence and I'm sure everyone else's also. Argh!!!
