Not that kind, everybody tells us about wood changing shape and size. I'm talking about picking it up and carrying it. No one talks about that, unless it's plywood. But plywood moves one sheet at muscle-straining, finger-crushing, toe-breaking time. But boards, if there is a glue up, you're moving at least two at the same time. How do you handle it? Carry one board at a time, or picking up a whole, maximum carry load?
