I have been to Atlanta, Colorado, California and Nevada and I have New York and Florida in the pipeline. I want to see more of the real America though, what states (and which cities / towns) do you recommend visiting? I absolutely loved Golden, Colorado and Littleton, Colorado and Denver, Colorado. Las Vegas is obviously a favourite. California was good as well. Actually, everywhere I have been was great.
I would suggest Philadelphia and Detroit would be wonderful places for you to visit, be sure to take lots of cash with you, and look visibly wealthy and out of place.
