Plaza Santa Domingo is where the illiterate used to go to have letters written. Today there are many small job printers as well as typists who are available for letters and forms. Ron is a friend of mine, originally from Fort Worth, Texas who has lived in Mexico City for ten years. We met at the Spanish Conversation Group held weekly at the Casa de Los Amigos, a Quaker Center and hostel near downtown. He says he swam the Rio Grande to get to Mexico.
