My city is pretty diverse. It’s not that big but it has a pretty standard northeastern mix: people of Italian, Irish, Polish, Greek descent, a large African-American population, a significant Indian population, a growing Hispanic population and multinational companies like Dupont and Astra-Zeneca have a lot of foreign workers working or just coming and going, and I encounter a lot of immigrants from all over but, mostly, West Africa. . It’s the land of ten or twenty festivals: St. Anthony’s festival, and the Greek, Polish and Indian festivals and it’s one big Irish festival all the time. :-)
I really love the diversity plus it makes for some excellent eating, all the varieties of ethnic cuisine around here.
