Nah, there's just nothing in Nevada between Las Vegas and Reno.

There seems to be ones in Reno, Elko and Winnemuca, that encompasses all of the traffic lights north of Vegas to be honest

they're working on putting a floating one in lake eerie, just full of fishing lures and diet coke.

I didn't realise that the eastern half of North America was so much more densely populated than the western half. Why is that?

My guess is it's just because historically most Americans immigrated from Europe and so they mostly just settled on the east coast, and they've been trickling across ever since. I'd be interested to find out, anyway.

Hopefully I'm not explaining this to another American, but the parts that are less densely populated (i.e. the Great Plains, Mojave Desert, Rocky Mountains) are that way--with the exception of the Great Plains--because their climes are not particularly suited for human life. The Great Plains were once more densely populated during the 19th century, but the Dust Bowl and agricultural overproduction forced a lot of people back to the respective coasts.

There's not much trickling going on. Most of the people who are out west are there out of sheer obstinacy or complacency and have been there a very long time.
