My grandpa was a card-carrying union carpenter. But all I remember is him doing general labor... all the actual carpentry jobs were gone before I was born, and I hit the half-century mark myself a few years ago. He worked with concrete and steel alot. I'd seen him put up cinder block too, picked that up somewhere I guess. And this was in the 1980s.

I'd take your bet, while trying to hustle you to raise the wager.
