When you move into a new house, you might get a plate of baked cookies, or one of those spiffy little welcome baskets if your HOA is on its game. But no, not if Laura and George W. Bush. Neighbors near the Dallas North Tollway and Royal have put out ‘welcome home’ signs in their yard. And it seems the signs are spreading south, so don’t be surprised if you see sign  pop up in a yard near you.
