In a Wednesday, May 2, 2012 photo, a house for sale sign stands beside a Hollywood, Fla. street as cars drive past. The cheap signs smashed into lawns and along the corners of busy intersections have vexed Hollywood Mayor Peter Bober for the past few years.   He now uses a software program that makes robocalls to the businesses, sometimes about 20 a day, to discourage posting the signs. The idea has been so successful they've seen a 90 percent reduction of signs in some areas and cities as far away as Canada are calling about the program.(AP Photo/J Pat Carter)
