Some thoughts on the May/June ‘93 issue:

On More Efficient Wood Use (p. 18):

We must conduct a massive educational campaign to wean the majority of builders and building inspectors (architects, too) away from their obsession with what I label 11th commandment framing. A recent poll by the NAHB shows 67... Read more
