Earlier quoted context omitted.
No-one has heard of Idaho, the potato state? >"Most US states are culturally and historically insignificant." // Someone said upthread. Thing is they're not culturally insignificant, I've no idea where Idaho is (NW?) but somewhere I've heard about its potatoes! That's because in the UK almost all the TV is from USA. Perhaps someone in a film, cartoon series, TV serial, song was from Idaho, maybe a country singer sang…
To clarify a bit, the existence of official state flowers and so on seems to mainly be a way for legislators to waste time. I have absolutely no idea what the official flower of any state is, including the state where I was born, and the one I live now.
I think that's the only one I (think I) know.
