Well, I rather go to the gym. If nothing else sure lots

If only half a yard of concrete is needed it is quite practical to use
a
small concrete mixer and mix it on site.
Even possible to mix that much by hand in a wheel barrow. Even for an
old
fart like me.
Beats going to the gym.

> Hi Brad,
> Just a couple thoughts on your concrete problems....Have you
considered

several

to

built...or
> rent a mixer and mix on the spot.....I recently had the base for my

the

several

really

to

lift

the
