Nice, when not using Ibc totes I use fence post also. It’s hell to drive them cause of rock but they work.
Nice neat stacks. Are you going to stack off the ground at a later time maybe. I am a T post stacker also.
Looks very nice for sure, & I don't wanna be "that guy" but as Mag Craft said, off the ground is better.
I've stacked on the ground many times and can get away with it here on the sand but yes, it is still better off the ground even if only a couple inches.
