From the piney woods of east Texas(beautiful, simply beautiful), to the arid semi-desert of far West Texas...to the beautiful areas of the Texas Gulf Coast, to the Great Plains areas. And the the Texas Hill Country is breath taking. What a choice to choose from.
Know one thing though. Everywhere in Texas, the winters are mild(what winter's the forum folks may say), but our summer's are hot, hot, hot! Some more so than others. And most areas are not immune to tornadoes.
