Descendants of those who remained in Florida were concentrated in the central part of the state. In the 1920s and 1930s, many Seminole established communities along the Tamiami Trail, a roadway completed in 1928 that ran through the Everglades and connected the cities of Tampa and Miami. The Trail Indians, as they were called, generally kept more traditional practices. They were less interested in establishing formal relations with the federal government than those Cow Creek Seminole to the north who started moving to reservations around the same time.
