Yesterday I found a local place that sold gravel that was also open on Sunday. No small miracle around here. Another truckload of gravel and the foundation hole is filled with some to spare for some inner fill later on.
After cleaning up the area, tools, and truck, I checked the clay/sand mix at about 4pm and found that it had dried out enough to make some more bricks. It was so late in the day they didn’t have time to dry enough to remove from the boards. They spent the night on the picnic table under a tree. They should be dry enough to cover by this evening in case the rain they are calling for tonight materializes.
