A lot of CA-6 to move
With a nod to Tennessee Ernie Ford I had two tandem loads of gravel delivered. The rock would serve as a base for concrete floor as well as keeping the job site from getting too muddy.

We a transit to make sure the gravel was spread evenly and in just an hour or so, the rock was even and smooth.
An experienced skid-steer operator could have had that done in half the time but I had the tractor and the help. I really don’t know how I could have done any of the work so far (and the work to come) without the tractor.
