In a few weeks, there will be only one town in Lower Fairfield County that does not have a Teen Center, a place where young people can socialize in an alcohol- and drug-free environment. And the town that will hold that dubious distinction is, most surprisingly, New Canaan. Long known as a great town to raise a family, the teen center was built by community members who believed that this facility would improve the quality of life for many in the community. Over the past 14 years, hundreds of students, parents and staff have worked on its programs and operations. Thousands of members of the community have participated in programs that varied from band nights to cooking classes.
