I agree with Google Maps on Cannonball Route

As a test of my contraction hierarchy code, and of an expanding database I'm building of US highways, I asked both Google Maps and my code to find a path from New York, NY to Los Angeles, CA. 

Looks like Google recommends going through Indianapolis, to Oklahoma City, then due West.

 My map isn't as extensive as Google Maps, but let's see what it decides to do:

New York, NY -> Indianapolis, IN -> Oklahoma City, OK, and on west to Los Angeles, CA. 

Better than I expected. I'll take it!
