I worked for my dad a couple summers when I was a teenager. He was a contractor doing wood frame construction in southern California. I never heard him swear so much as when the plans called for something that was next to impossible to build. Later on I did some framing work on my own. Ran into several cases where the designer completely ignored the dimensional instability of wood due to changes in humidity. Often that was really hard for the "no education" guys to fix.
