The Hill Country is really nice and Luckenbach is a must! If for no other reason, just to say you where there.
FYI. If you enjoy a great burger, the Shade Tree Saloon & Grill in Spring Branch, Texas, on Hwy 281 north of San Antonio and south of Blanco, is the place to go. A great biker bar with the nicest group of retired professionals who let their hair grow and enjoy life.
