Just had this number try to call my cell.  I don't answer unknown numbers from out of province (I am in Manitoba) and I doubt very much anyone I know is in Huston Texas and knows my cell number as I don't give it out to many people.  Most likely this is a new telemarketer number or fraud attempt.  Added to my address book as 'Do Not Answer'.  My suggestion to everyone else, don't answer if you see it on your cell...
