Any idea where I could dispose of old worn US flags? I have a 3x5 one displayed from my front porch/entry at all times, but they become worn after about 6 months. I fold them up and store them after I get a new one. I used to drop them off at the Home Depot or Lowes where the Boy Scouts had a box for collecting them for proper disposal. Now they don't have that any more. I live near Grapevine/Flower Mound/Lakeside area north of DFW airport. Anyone know of an organization nearby that collects and respectfully retires old flags?
