I might have to say that the one combination I probably love more than geography and zombies is geography and pizza. I have a tattoo about pizza that is too embarrassing to share on the internet.
Flowing Data used a data set of closest pizza places in a 10 mile radius to create various maps showing distribution of popular pizza places.
The blog post also gets into some thoughts on regions and migration of ideas when making suggestions about why the pizza places are as popular in different areas as they are:
Regionally, Papa John’s, which started in Kentucky, is strong in the east central area; Godfather’s, with headquarters in Nebraska, is popular in the midwest; Little Caesars shows strong in California and Michigan (its first location in Garden City, Michigan); and Papa Murphy’s is strong in the northwest, which makes sense because it started in Washington.
A few years ago, Floating Sheep created what they call the “Great American ‘Pizza’ Map.” It’s a very interesting map that plots out internet user references to pizza, guns, and adult clubs. In the comments there are the start of some great geographic discussions and questions around culture and location, but since it refers to adult clubs, I’ll let you decide if you want to draw from that resource. Maybe for the much older kids. However, the Pizza Place Geography maps at Flowing Data is a great resource to give to students. Just know that it will make them hungry.
