Asking "what should we do today" gets a lot easier with more than 200 destinations on hand. Lori Litchman organizes Pennsylvania's best outings by theme, from American history and homegrown makers to outdoor adventures and offbeat sports, so the plan follows the mood rather than the map. Arboretums, waterfalls, birding spots, and antique shops all get their due. Handy enough for the glovebox, it turns a free afternoon into a destination.
