Apparentely everyone hasn't seen the movie 'Balto'.
I'm pretty sure that's a cartoon movie based around a husky that carried some medicine in Alaska. And I know this, being from Alaska. I don't know what husky has to do with anything.
everyone or so I thought, seems like I severely overrated the average intelligence of the common man
Knowing about makes some random stone structure in a Iceland is the definition of intelligent? Wow, news to me.
I bet I can name off a lot of I consider "common knowledge" that you wouldn't know, but it still wouldn't make you any less intelligent, just that my definition of what's common doesn't exactly fit with everyone else in the world. Different people from different places know different things.
