Book excerpt: The common backyard swingset or treehouse or jungle-gym will never go away, but today's recreational landscape is also likely to have a full-featured sports court, a putting green, an outdoor kitchen for grown-up entertaining, or a board-game gazebo where the adults play bridge or mahjongg. Here, in one comprehensive book, are more than 25 complete DIY projects to create play spaces for family members of all ages--toddlers to old-timers. Also includes a detailed appendix giving rules and dimensions for all the popular lawn games, such as badminton and croquet. This is an ideal book for consumers traveling less and recreating at home more.
