It is difficult to define Texas as a whole because the state is really diverse. So, I will divide the state into regions by culture and geography:
East Texas: Basically anything to the east of I-45 is East Texas...Culturally similar to other southern states. Huge amount of
confederate flags and rednecks. Everyone's obsessed with high
school football, Baptists rule
everything.
Geographically, It's flat with some sprawling Pine Forests in the Northeast. Climate is hot and humid. There's three seasons here: Summer, Almost summer, and Spring. The main cities are: Beaumont, Texarkana, Lufkin, Tyler, Nacogdoches, and Port Arthur.
Central Texas: Beautiful Country, abundance of rolling hills and gorgeous streams. Often ignored by other parts of Texas.
Schlitterbahn(voted best waterpark in america) is there. Climate is wonderful, it's warm and dryer than other parts. Major cities: Austin, Temple, Kileen, New Braunfels, and Waco.
North Texas: This mainly Includes the panhandle which is mainly similar to the midwest. It's really flat with almost nothing but farms and grass. There is beauty close to Palo Duro Canyon. Major Cities: Amarillo and Lubbock.
West Texas: Arid but beautiful. This is the sterotype that most people have about all of Texas. It is mainly a part of the Chihuahuan Desert(which is not a dog) and is really beautiful around the Big Bend areas. Hot and Dry, this region is similar to
the Southwest. Major Cities: El Paso, Odessa, and Midland.
South Texas: Mainly farming and ranching areas. Not much here but the Rio Grande Valley. Huge influx of Mexican Immigrants. King Ranch is here which is bigger than Rhode Island. The main tourist
attraction here is South Padre Island which is the only place in Texas where you will find clean beaches. Major Cities: Brownsville, McAllen, Corpus Christi, and Kingsville.
Urban Texas: Includes the areas of Houston, Dallas-Ft. Worth, and San Antonio. These areas have a culture of it's own and don't normally conform to the areas they're in.
