(Bad) Opening Paragraph:
All the flags were out in front of the houses and stores in Rainbow Center on Memorial Day, as Boyd Mason drove his Buick back from a real-estate trip to Kentucky, and parked on the east corner of Peninsula Drive and Crest Ridge Road, at the side of his sister Alma’s house, where he had lived since his wife’s death twenty years before.
(My Mentor Howard Pease continues) This one-sentence paragraph contains more than a dozen facts, at least half of them not important enough to be included so soon. When you overload a first sentence or paragraph with so much information, your reader is apt to come up so wobbly and bewildered that you lose him. Therefore, prune your opening paragraph until only a few important facts are given.
