D on’t have a “Big Mac Attack.” Rockdale’s McDonald’s isn’t going away after more than 22 years. In fact, it’s coming back as a newer, larger restaurant. But first you’ve got to tear down the old one and that’s what happened early this week as demolition crews took down the familiar fast-food eatery that first opened on Dec. 11, 1990. Plans are to build a new, $690,000 facility. Employees of the Rockdale location have been reassigned to work at other McDonald’s around the area.
