I don't know about the curriculum in other states and what exactly they learned about, but we didn't learn fun facts or current events or anything. We studied the Oregon Trail. Of course, we'd already had years of experience and practice in regards to the Oregon Trail, thanks to that awesome computer game you all know you played in elementary school.
The point is, I didn't know a lot of the "official" state facts of Oregon until I'd moved out of the state in which I grew up. I didn't even know there was an official state song ("Oregon, my Oregon") until I was 21, although when I said this to my parents at the time, Dad insisted he used to sing it at the border on family vacations. Don't recall that one, Dad. Sorry.
Here are some of my favorite Oregon Official State Facts:
With all the breweries in Oregon, this pleasantly surprised me.
Flower: Oregon Grape.
I was slightly confused on this one, because the name doesn't sound like a flower ...
Motto: She Flies With Her Own Wings.
This kind of sounds to me like the phrase, "Walk to a beat of a different drum." For anybody who's been to Eugene, you know that's true.
Tree: Douglas Fir.
I knew my car's name sounded familiar.
Huey Lewis was right. It is hip to be square.
Sing it with me: "Hail to thee, Land of Heroes, My Ooooooo-reeeeeeee-gon." (pronounced "gun", NOT "gone")
