Strong possibility that this is yet another spoofed number.  Based on time of day, no name on my caller ID, no message left and a calling area in Florida where I do not know anyone.  

They called me too.  I don't know anyone in FL.  I didn't answer and there was no message left.  It's either a wrong number (yea, sure) or some creepy telemarketer idiot.  If they don't have the class to at least leave a message, they'll be blocked!
