[TowerTalk] Mixing concrete for a base

[Blake Bowers]

There is such a thing as a false economy - but I think
it would be difficult to finish 2.5 yards by hand, in a
timely manner.  Such a pour should be done in one shot,
that is going to be tough.

If you have any value on your time, adding the cost of
materials, etc, you quickly cost more than the price of
redi-mix.

Although some places have a 5 yard minimum, most of
those will deliver 2.5 yards, with a extra delivery charge.  Most
of the places I have bought concrete in the past 6 months,
NY, PA, OH, MO, and OK, have been right around 75 bucks
a yard, plus a delivery charge for under 4-6 yards.

Cheaper to call them for me!
