If one were to grab something labled 2X3, what might one reasonably expect the dimmensions to be? 2X3 no? Well, no! Try 1.5X2.5. What about the fabled 2X4? Why, of course that measures 2X4 you say? Nay, I say. 1.5X3.5!

shrinkage? Maybe it was a cold day.
In our cabin we have 2x4's that are actually 2 inches by 4 inches. Also watch out for lengths. I went to get a 2x4 that should have been 8 foot long, instead of 96 inches it was 92 inches. More shrinkage?
