I will do my best with South America: Columbia, Suriname, Venezuela, Brazil, Argentina, Chile, Uruguay, Paraguay, Peru, Bolivia, Ecuador, French Guiana..and I can't think of the last one.
OK, now onto the US states, which we had to memorize in school: Alabama, Alaska, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin, Wyoming.
To prove I didn't google these, there is one state missing. My apologies to that state because for the life of me, I can't figure it out right now.
Now editing in Missouri. Sorry Missouri. I always forget one of the states beginning with "M".
