It is done. I'd over-estimated the space. Pacing it off, it turns out that it's only 450 square feet (30 x 15). The roll of landscape fabric I purchased says that it's 400 square feet so there are a few patches of earth that aren't covered. I've kept those near the house where possible as that's the part that gets the least water and, hopefully, where things are less inclined to grow.
Used some of the rocks I dug up to help keep the landscape fabric from blowing away in the strong wind that's kicked up. Feels like we might get some rain by morning.
Now, though, I am off to the shower to douse my sweaty, dirty self. Then, relax in front of the Twins game with a cool beverage.
