Life is a highway

To compliment yesterday's post, I thought this was pretty cool: a map of all the streets in the lower 48 states. That's it, just the streets. No outlines, no borders, nothing but roads.

I thought this was so beautiful, yet so interesting; the map is divided almost equally in half. The roads are much more sparse on the western half of the US. And they abruptly end--there's no gradual fade or anything.

The major cities almost remind me of the constellations--look south of Chicago and you'll see what I mean. I also love the swirls defining the Appalachian Mountains. Very, very cool.
