Let's see: So far, I've been to:
Other countries: Argentina, Bermuda, Canada, England, France, Italy
(would love to go back and see more of all of them!)
In U.S.: Hawaii, California, Arizona, Nevada, Washington, Illinois, Minnesota, Wisconsin, Indiana, Ohio, Texas, Utah, Colorado, Nebraska, New York, Pennsylvania, New Jersey, New Hampshire, Vermont, Massachusetts, Connecticut, Rhode Island, Washington D.C., Virginia, Maryland, South Carolina, Georgia, Florida.
Side note: My DS's 4th grade teacher last year was just wonderful for a thousand reasons. Here's one of them: she's a single mom (in her 50s) and she had promised her son that she would take him to all 50 states before he went to college and she did!. (and just "driving thru" didn't count) She finally finished when he was about 17 yo. (They went to Hawaii.) Her DS is now a freshman in college. I thought that was a terrific idea and shows, even if you have a limited budget, you can cover a lot of ground--literally!
