I've only been abroad one time, and there were little gecko/lizard things everywhere, climbing up walls and scurrying across roads, and nobody cared. I was constantly fascinated but to the locals they're just kinda there.
Bonus question to anyone who visited the UK - was there anything that fascinated you but I'd be taking for granted?
Kangaroos and wombats are dangerous when you're driving at night.
To be fair, I'm probably unique in my apathy toward, borderline dislike of, platypuses. When I'm out fishing and I see a platypus I pack up and go somewhere else because I know I won't be catching any fish.
