Throughout the summer of the staycation, we found ourselves up in McKinney every few weekends, even if only for breakfast at cozy Spoon's café or a walk through the Farmers Market planted among ancestral McKinney homesteads in the historic district. But a trip to The Book Gallery is an essential part of any visit, especially for the bibliophile who needs a break from poring over Half Price's estimable stacks of oldies but goodies. Encased in glass are first editions by most of the masters you can tick off in the next 20 seconds; we've long coveted the Hemingways and Fitzgeralds and Wrights and Salingers and Dickens...eseses in desperate need of our liberation and affection. They're not too pricey either; we just spend our hard-earned pennies on the estimable collection of Dallas-related books nestled in the local-interest section near the back of the shop. Here's where we picked up Lon Tinkle's essential The Key to Dallas, as well as a first-edition of the Dallas Historical Society's 1978 coffee-table book Dallas Rediscovered: A Photographic Chronicle of Urban Expansion, 1870-1925.
