Is Hot Dr Pepper Really An Oklahoma Tradition?

Having traveled the country and sampled just about every weird dish I've come across, I can't imagine sitting down to intentionally drink boiling hot Dr. Pepper. Is this an Oklahoma and Texas thing?

Obviously, every region around the world has its own food culture and traditions, but Dr. Pepper used to advertise this hot beverage around the country. It doesn't seem like a location-specific type of thing at all.

Dr. Pepper even managed to get Dick Clark on board with it in their national advertising back in the 60s-70s... but if they offered me a check to talk about how awesome boiled bull testicles were, I'd do just that for the right amount of money too.

Initially, I thought hot Dr. Pepper was an old-school thing. Like some brilliant mind working for the soda makers found a way to sell more Pepper to counteract the winter lull in soda sales or something... but Dr. Pepper still talks about the cold-weather drink to this day.

If you look around the web at the different "recipes" for hot Dr. Pepper, you're bound to find differing opinions. Some say it's best with a cinnamon swizzle stick, others mention the merits of adding brown sugar... as if it doesn't have enough high-fructose corn syrup in it already.

Either way, I'm an adventurous eater and I'd probably try it, how bad could it actually be? I know I'm not the only person who has drank a hot can of DP to quench their summertime thirst. Moreover, now I'm curious how big the burps will be.
