As I'm traveling to and from work I note that I am surrounded by Take Out Restaurants everywhere I look. Collecting take out menus is not something that these vendors are going to complain about. They want you take them because that's how they make their living. They want you to call and place an order. I would only be taking one menu from each place and there is such a variance of food available, something could be done with take out menus. Take out menus becomes another focus of data collection.
