Roads, streets, highways, thoroughfares, lanes, etc, of the USA.
Well 48 states of it, anyway.

All of the streets in the lower 48 United States: an image of 26 million individual road segments. No other features (such as outlines or geographic features) have been added to this image, however they emerge as roads avoid mountains, and sparse areas convey low population. This began as an example I created for a student in the fall of 2006, and I just recently got a chance to document it properly.

That's it, just roads.
I wonder how much heat is retained by all that pavement?
I wonder how many reptiles get squashed basking in that warmth?
I now know why the chicken crossed the road, however, it had no choice.
