Aliens who are covered up by the government. 

Like on of my favorite t.v. shows once warned, "Trust No One".

That's creepy.. maybe area 51 or the Nevada test site..

You've never seen anything like this? 

It was so strange. I was staring out of the airplane window bored with the landscape.  I mean after awhile all you see is vast areas of sand and cracks. All of a sudden that came into view.  I was thinking, "Dude!  It could be some sort of message to the Aliens an' shit!"  LOL!

Nope.. never seen anything like that.. other than stuff on national geographic about crop circles and the Nazca lines in Peru..

 

Maybe you stumbled across a conspiracy.. lol

 

Oh no! Men in black suits are going to come knocking on my door!  Yikes!

now that we've all seen it...you've doomed us all!!

Yep - an alien spaceport for sure!

Damn aliens! 

No, damned Homeland Security!

They'll let anyone into this country!!

 

Did you know it's against Federal Law to harbor an alien being (as in UFO type alien)?

But as far as I know, no one has ever been prosecuted for violating that law. 

Hmmmm.

They're using them for their technological advances.  I mean come on, teflon?  Think about it.

Since they're letting them breed with humans, no one knows who's human or who's a hybrid.

myclette, most likely those are old abandoned (or maybe even active...hard to tell) bombing test sites.  The Nevada desert is filled with that stuff.  I did a google on "circles in nevada desert" and found a page on the GoogleEarthHacks forum where people posted bunches of aerial satellite images of these markings on the NV desert floor.  In some of them, you can see remnants of old buildings, and in some there are still aircraft and vehicles there.

OMG....I was right and I hadn't even read your post!!!! That just goes to show I've been watching too many military aircraft shows with Ryan. That boy loves planes.

That's so cool! I knew as soon I saw that you'd replied, you'd have the answer!

That's me -- a veritable font of useless trivia!

It looks like targets for aircrafts to test launching missles.

Or it could be where the aliens play baseball.
