There was no sarcasm being directed at anyone, it was a tongue in cheek gesture with rg acknowledging that its a big desert and there is a very good possibility that other things are hidden there.

some people just don't want to acknowledge this undeniable truth. Whether it’s old news or not it’s a fact that should be brought up to remind people that there is a lot of stuff out there that can’t be seen from an air conditioned Land Cruiser window.

The sad thing is diggin those jets up were not front page headlines except on Fox News.
