7-11's carry Dr. Pepper flavored Slurpees.
Every fast food restaurant I've frequented has Dr. Pepper on tap.
Southwest Airlines offers both diet and regular Dr. Pepper in their complimentary in-flight beverage service.
From a press release I found here
"In comparison, other areas of the country are under-developed in Dr Pepper consumption, such as in the Northeast, upper Midwest, Northern California and Florida."
"There is no reason for Dr Pepper consumption in these areas not to be at least at the national average,"
"When we achieve that goal, Dr Pepper will be well on its way to the billion cases annually set as a goal by the end of 2009. We doubled volume in the last decade, and I see no reason why we should not do that again by the end of the first decade of the 21st century,"
