ideas for my fieldwork for my anthropology class?

[Stardust]

i have to do fieldwork where i study some sort of "people". i WAS gonna do some elementary school kids, but my teacher said no, (18 or older people), so i need ideas, like i know someone studying homeless people at a shelter, and another one studying March Madness in high school seniors (when they get acceptance letters for college), another example is studying people at a chuch (christians there)

any ideas (can't be affiliated with my college, like studying a sorority or sports team though), thanks in advance!
