I grew up mostly in (Northern) Virginia. For various piano competitions, I visited Maryland and D.C. (guess that's not a state). For school, we went to Pennsylvania to check out our nation's birthplace. While vacationing with the fam, we drove down to North Carolina. While visiting colleges, we visited Massachusetts, Connecticut and New Hampshire (and drove through NJ, Delaware and Vermont). While flying to Japan, I connected through airports in California and Hawaii (weak, I know).

That's about it. Including DC, that's 13 states... but most of those were short trips or airport connections!

How many states did you visit before graduating high school?
