Map of Every Fast Food Burger in the US

This interesting map of US fast food burger joints was put together by the folks over at http://www.weathersealed.com/.  Great work!

Fast food burgers may be delicious once in a while. But what if you lived in a neighborhood that had no other inexpensive food sources?  I'd like to see map of farmer's markets and grocery store chains laid on top of this, to see where fast food restaurants dominate low cost fresh food stores.
