I would love to visit Argentina, it's in the southern half of South America. Tropical!
I've never been there! Is it sparsely populated?
It's the 8th largest country in the world and 2nd largest in Latin America and the largest Spanish speaking country. It's definitely well populated
I didn't realize it mainly had Spanish speakers! What is there to do there? Any attractions?
The earliest humans date back to the Paleolithic period so there's plenty of historical attractions as well as new ones
That is cool, I may have to visit there someday!
Argentina claims sovereignty over part of Antarctica and the South Sandwich Islands, which I think is interesting and a little funny
That is kinda humorous! Haha
They are set up much like us. There are 23 provinces that have their own rules but overseen by one main federal system. 
Wow!
