You may be randomly selected (as in the flip of a coin) to receive a letter asking you to participate in the Photovoice project. The Photovoice project is an activity that will allow you to express your thoughts and feelings about your neighborhood through pictures that you and your child will take of your neighborhood. You and your child will take pictures of your neighborhood with a camera provided to you by the study staff. The pictures will be developed by the study staff and they will bring them back to your house. You and your child will then participate in an interview to talk about the photographs you took. This interview will take about 20 minutes.
