The brew went well today. In fact, I'd call today the Most Successful Day This Week. Local homebrewer Tom Froehner came by to lend a hand; in fact, I made him do most of the work.

The only thing that went "wrong", if you can actually call it that, is that I overshot my original extract by quite a wide margin. The target was 10.2°Plato, but I ended up with 13.5°P. This isn't the first time this has happened in recent brews...looks like I need to adjust my recipe calculations a bit.
At the end of the day, we had brewed seven barrels of Bugeater Brown Ale and cleaned everything up in about 6½ hours. A good day.
