I haven't been to that many states, but here is my list -
I have lived in multiple locations in Wisconsin my whole life.
I have visited Montana (x2), Idaho, Wyoming(x2), California, Oregon, Washington, Iowa, Minnesota(x12), Illinois(xUnknown), Michigan(x2), Indiana, Ohio, Pennsylvania, Maryland, West Virginia, Virginia, District of Columbia, South Carolina (x6), North Carolina (x2), Georgia, Florida.
My list is a bit short because we never drive to destinations so I don't get to add the states we drive through.
I have also been to Canada. My parents have been to every state in the union and several foreign countries.
