The town where I grew up had three HS Greek organizations, two fraternities: Delta Sigma and Sigma Phi Omega, and one sorority: Delta Beta Sigma. All three were national organizations. They were not part of the high school, they were part of the town, and drew students from all three local high schools. DBS folded in the early 90s in my town, but still exists on the national level with 13 chapters. The two fraternities gradually lost members until they closed the chapters, but they also have chapters scattered throughout.

The sorority rushed in the summer before school started, and the fraternities rushed in the fall. All three had informal rush in the spring semester to bring in a few members that had been "missed" in the fall. They had adult sponsors, alums who were actively involved, and national rules. Students were not allowed to wear letters to any of the high schools.
