Not enough detail for an accurate diagnosis, but I suspect it's crabgrass,
an annual. *If so, your choices are mowing practices and fertilizer or
chemical warfare.

I'm 99.9% sure it is not what most of us here in the Midwest call
crabgrass. I have a few patches of crabgrass, but nothing like the
number of patches of what I showed in the picture. I hope to get a
sample to our local Morton Arboreteum, and see if anyone there has any
ideas. But, I'm not too hopeful as they are primarily interested in
woody plants and trees, not grasses.

If you have any sense inside that skull of yours, you will listen to
what Kay Lancaster has told you. She is very good at this stuff. It is
your best chance. Do as she says, or it is all on you.
