Considering ants and other insects of South America make the Zerg look tame, that's one reason to not want to visit. Still curious about Rio De Janeiro though.
If mexico was any indication of how much worse it is south of there, that's horrifying.
It's quite enough to have to check your outhouse hole or public toilets for brown recluses to avoid bites on your choicest bits every time you have to go.
Or the myriad of wonderful diseases on practically every surface there.
Or deal with venomous scorpions being in everything and have to check all the time if a lethal sting isn't awaiting you around the corner or in your shoe.
So I'll take a scum shack in America any day.
We'll murder them all, amid laughter and merriment...except for the few we take home to experiment!
