Don't forget that The United Mexican States make up a significant part of North America also. The US is the middle country in NA. In fact, I competed in the IFBB North American bodybuilding Championships back in 2010. And it involved all of North America. The competitors were the top bodybuilders from Canada, Mexico and the US. It was awesome. But it was hard getting used to groups of guys around you speaking French or Spanish and not knowing what they were saying.
