GOOD has posted a light map of every McDonald's in the country. I'm not sure whether to be impressed or scared. According to the blurb that ran with the map, the farthest you can be from a McDonald's anywhere in the country is 145 miles at a point in North Dakota. I guess the pancakes at McDonald's aren't up to snuff.
I've copied the image below.

It would be also interesting to see a map like this of Subway considering the sandwich chain's recent boast that it is about to surpass McDonald's as the most proliferate fast food chain in the world. Currently, Subway operates about 31,800 stores and is rapidly closing in on McDonald's mark of 32,158 stores.
