In Virginia, fresh-faced, environmentally minded schoolchildren gather biological samples and test water quality in rivers and waterways, part of the Izaak Walton League's Save Our Streams initiative. In Chicago, amid Tai Chi classes and body massages, families with young children enjoy performance art and teenagers flock to an all-night "rave," all part of the Museum of Contemporary Art's Summer Solstice weekend. In Minnesota hundreds of children with HIV or AIDS come together each year at Camp Heartland, where they can "escape the isolation and misunderstanding they so often face because of this illness." And all of these kids can thank the caring people at Philip Morris.
