Wow, I remember a wildlife biologist complaining about the light pollution and impact on wildlife when I was working.
It does look that bad on the ground!!!
Otherwise, some areas that I am familar with appear to UNDERESTIMATE the extent of light pollution.
Thanks for the posting.

Since each zone is a factor of 3 in sky brightness, breaking each zone in half amounts to ~1.7x factor in sky brightness. This is a *great* tool for site scouting when you're looking to squeeze out every last bit of darkness for your 1/2-hr / 1-hr / 2-hr drive to an observing site.
This map has been around for a few years, but the one thing I can't find is a Google Maps overlay of the expanded color scheme. Anyone know of such a beast?
