If you have a helicopter and a burning desire to visit all 478 KFC locations in California, give this to your pilot: https://dl.dropboxusercontent.com/u/22934979/CA_KFC_LK.jpg. I used the 2D Euclidean distance between each location and the Lin-Kernighan heuristic [1], so scaling it out to the entire U.S. wouldn't be hard if the data was available.

Now uses the the Concorde cutting-plane-based exact TSP solver.

Edit: I really should have named the repo colonel-sanders.
