STL High School Sports Local St. Louisans, this one is for you! Our Arch City has an extensive parochial and private school systems, and your neighborhood isn't always the best way to establish grounds with a new friend. We evoke a lot of teasing from the out-of-towners when we ask "where did YOU go to high school?" but it's how we figure each other out in this town... and to our alma maters we will always be true!
