TEXANS HAVE ALWAYS been highly susceptible to the call of the open road, and nowadays that call is stronger than ever. Not only do car trips celebrate independence (you decide when to eat, stop, or frisk yourself), they also embrace the Zen-like notion that the journey itself, not the destination, is the thing. And journey we did, over the hills, through the Piney Woods, across the plains, and hugging the coast. Along the way we discovered the riches of ten wildly diverse routes, from inviting restaurants and inns to oddball points of interest and sites steeped in history. So what are you waiting for?
