Book excerpt: Each week for the last eight years the readers of a small-town newspaper in Ohio have been treated to the not-tremendously-dramatic but always humorous adventures of Natalie and Mark, a sixty-ish couple living out their dreams in a little old house on East Mulberry Street. Here are some ninety of those adventures arranged in a compact volume, ready at a moment's notice when you need a laugh. Topics include cats, marriage, automotive rust, gardening, elderly parents, food, and why you might wish to avoid hand-waxing a locomotive. And, of course, love.
