Was there a UFO in Robstown (near Corpus)?

Some people are visiting TexasUFOSightings.com via a search for a recent Robstown, TX UFO (possibly on February 19th, a few days ago). However, I can't seem to find anything about it on the web. I do know that one of the best mass sightings of 2013 so far did occur in nearby Corpus Christi recently. Could these sightings be related? In Corpus, a gray disc-like craft caused drivers to stop their cars and look up to the sky. Pictures of the smoky trail the craft left behind were snapped.
