Nah, I've been really careful most of hte time, but, as usual, I got in a hurry and didn't think. Moved the tape measure to make my measurement (to 2 inches, to be more precise), then didn't think about that on the other end. Hey presto, board 2 inches shorter than I wanted. But a nice straight, well measured 2 inches shorter...
