walk from Mexico to Arizona.

You do realize that Mexico is not in South America?  The walk you suggest would actually be thousands of miles from Brazil to Arizona.  Many more hoops than traveling from Big Island to Oahu. (including but not limited to flaming hoops, multiple border crossing hoops, hunger hoops, dying of thirst hoops, riding on top of freight car hoops, dengue fever and other illness hoops)

Mexico is not South America, but South Americans are going through Mexico.
