Graham, you are paying attention. We have the first 4 sets of holes ready for cement, and I also have the North West corner sonotube ready, but a long ways (50 feet) from the rest of the building.
So, we decided informally yesterday that with 8 holes ready, they are the furthest east toward the railroad, we can assemble that end and even use it. We can then finish the rest of the 80 feet in warmer weather between use of the facility, or possibly even before the first scheduled use. That is what Dave and I had a quick discussion about yesterday, and is the best possible outcome this late in the year.
