Those types of things will definitely help, but it is a constant concern which is why I considered it difficult. A summer camp or community program which attracts all kinds of kids would be ideal, but it is a relatively short period of time compared with the 9 months of daily melting pot sessions in a typical public school. Additionally, if "summer camp" means a highly specific camp (like art camp, or theater camp, or Southern Baptist Christian camp), the benefits will be lesser. So, the difficulty is not in finding some amount of diversity, it is matching the level many public schools offer.
