Texans love their beverages, whether it be iced tea or beer that is barely drinkable, the citizens of the Lone Star state seem proud of their drinks. Sodas aren't called such here. They refer to every kind of pop as "coke". This is a conversation you'll hear frequently in Texas.
Him: Would you like a coke?
Him: What kind?
For whatever reason, the word coke is used to describe any kind of soda, sort of like how U-haul is the end all word for any rental truck.
In the Northwest people certainly enjoy their sodas, but very few restaurants actually serve Dr Pepper, well at least one's that don't include a drive through window. In Texas, you'll be as hard pressed to find one that doesn't offer the tasty beverage as you would be finding a home that doesn't have a firearm.
The love for Dr Pepper is not shocking, as it was first conceived in Waco, and even has a museum located there dedicated to its goodness. Texas may love it for regionalistic reasons, or they just love it because the whole state is addicted to sweet drinks, or it could be a combination of both. As you can imagine Texans love all things Texan, so it makes sense that they want to be a Pepper.
The company has offered all kinds of different flavors, but its original is the favorite of Texans the state over. I'm not a big fan of the drink myself, but its not something I despise.
So tip a glass to the the favorite soda of Texans, Dr Pepper.
"I've always maintained you cannot tell anyone what Dr Pepper tastes like because it's so different. It's not an apple, it's not an orange, it's not a strawberry, it's not a root beer, it's not even a cola. It's a different kind of drink with a unique taste all its own." - WW Clements
