Let's see here.......we only have 2 NIC groups, 0 NPC (just can't keep 'em here, hehe), and the rest are local.
We also have never had any "multicultural" or "historically black/white/whatever" groups either. Even though Rio is a hillbilly school, we've never had any real "trouble" with having greek members of ANY racial/ethnic/socioeconomic background.
Hell, my own sorority at one time (for a large number of years)was the "Japanese" sorority for awhile

Hence my screenname,
