I'm sorry. Us old people can't figure that kind of stuff out.

When I was at a yard a few years ago, they were telling my husband and I about the A, AA etc. they were big rocks, not little at all.
I have pea gracel in there now. It has all sunk in. Plus, the guy behind me insists that I have to have big rocks. As much as I think he is just a jerk, his family does own a large dairy farm. They are the owners of the stupid guineas that keep coming into my yard. He really does know a lot about animals. Though, that does not mean that he is right. It does mean that he will refuse to sell anything to me if I disagree with him.

He charges more than the other landscaping yards around here too!
Anyway, I just want to have good drainage always. As I keep saying, this is a now or never kind of thing. I just don't see myself bringing tons of rocks in through the door later.
