Being from Kansas City I've never really thought about how people get confused about what state its in but I can see where they are coming from.
#1 - So the city of Kansas City is in the state of Missouri and not the state of Kansas?
#2 - Yes. But there is also a Kansas City Kansas but its smaller.
#1 - Gotcha, so most people from Kansas City live in Missouri?
#2 - Well yeah, if they are literally from Kansas City MO they are from Missouri but in the metro like 1/3 of the people live in Kansas.
#1 - This is too confusing, I'm not going to waste any more of my brain power on your flyover city.
