You could reduce the concrete volume by defining a space inside - maybe a
smaller sonotube with plywood lid. Lot less moving heavy weight, and
portland dust isn't nice. Rebar would anchor the poles.

Upon closer reexamination of the project, I have decided to use a 18" strip
of concrete along one wall to rest plates on, and to do the Sonotobe bases
on the other two sides. This is in a recess in the back of my house, and I
will have to back in the mixer with the ATV. I think for this one, I shall
just use bags, and not schlep all that heavy other stuff in there.

My main question, which you and only a couple of others was how fast can I
mix and pour this so I don't come up with a layered pour. Yes, I will weld
some rebar to the poles, as always.

Thanks.
