Here are two additional bits of progress.

The first is the pad for my factory and warehouse. I’ll put the buildings out once it’s dry, possibly tomorrow.

And here’s a dirt/gravel road idea I’ve been wanting to try:

That’s two pieces of plastic door trim, painted with exterior paint to protect from UV, buried in the soil. Then I dug out between them and added rough sand to serve as gravel. I hope that these edges will help keep the sand in place so the road doesn’t disappear in the first rain.
