The sage-like city prowlers of Inside Detroit lead groups of tourists and natives through Detroit's history-rich hubs, charming watering holes, and evolving cultural centers. Walking tours bring urban nomads through the major landmarks of Detroit's downtown, such as the underground railroad's Second Baptist Church and the 40-story Guardian Building, an Aztec-inspired architectural masterpiece built during the 1920s, when it was thought to guard the city from hay fever.
