Google Earth

Google Earth Pro is a really cool program.
But I noticed today that it does not display power lines - I mean the BIG ones.
I wonder why that is. Wouldn't they show up in the satellite photos?
I can tell from the satellite photo of my house that our oldest daughter was visiting when the photo was taken, because we can recognize her car.

Maybe they’re not shown for security concerns?

Well, the lines I'm talking about are connected to this, which I copied from Google Earth (including the label). I kind of doubt that security is their concern.

Check this out. Power lines clearly shown emanating from the Bonneville Dam, up my way.
