NICE DAY out there today. Jiji, after a walk around the IBM building and a glance at the waverunners tearing up and down the canal and the power boaters, chomped down a doggie Oreo and strolled home. I kept her company on my bike. Now, she lies in the sun, taking it easy. Me, too. This is my last weekend before I am tossed into the copy pit. Our final Weekend Beat installment came out OK this morning. OK, means, at the the very least, no errors. The first thing I do every Saturday is get the paper and check the pages in my section for "pullbacks"— typography marks indicating the page was yanked back for a fix. In our case an ugly (scary if you are the editor) bullet above the folio line at the top of the page. So, bottom line—in the four plus years I have worked the section we've had only one pullback and that was a least three years ago. A good record. However, no one in their right mind would give me a Pulitzer for proofreading—I had a great deal of help from my immediate superior to editors in other sections of the paper. Thanks to all.
