IN and ON

I grew up ON Long Island but now I live IN Brooklyn which is ON Long Island so I tell people I live ON Long Island but not IN Long Island because I live IN Brooklyn but when I visit my family IN Suffolk I tell people I am going OUT to Long Island and when I am there and texting my friends who are are ON Long Island I tell them I am IN Long Island so they know what I mean and we can meet up to go fishing.

Fight me.
