We saw this huge thing that looked like a big white spaceship way off in the distance. When we got closer you could see what appeared to be stairs going up to the nose of it. Sure looked like we had been invaded by little green people.

Ended up being a Border Patrol tethered surveillance radar blimp. It is tethered via a 25,000-foot cable. Sure puts a different meaning into the word surveillance. Wonder how they keep planes from flying into the cable?
