We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I look at that black stuff in awe and wonder if you could bring over a few yards3 of that when you drive west on I-70 (the old Grand Army of the Republic Highway), Grand Junction, CO.
In my desert area, the 4" of a lean organic layer we call 'topsoil' is pretty good and we are quite proud of it. We put almost anything on it to hold the water. Even after several years of soil improvement, I am sure our upper profile looks like what you would normally discard.
That lovely mulch makes my mouth water. Down here, our soil is made up of equal parts petroleum and glue. Takes years to improve it enough so most plants will flourish. But if something will grow in it, it can grow anywhere.
