Managed to get about half the concrete poured. It's really a three-man job, but I can do it myself, it just takes a hell of a lot longer than I thought. I figured I'd be done in a couple of hours, and I'm halfway done in three.
So far, three loads of ~150 lbs. of concrete poured and struck.
And I really need a shower.
Glucerna shake for dinner. Tastes like chocolate plastic. Glucose is back down to still-high-but-reasonable. Gonna snarf some fiber and shower, then bed.
