Just this past week, I was trying to recall how many US states I've been able to get to in my lifetime, and it prompted me to write them down (the ole memory isn't as sharp as it used to be). Here's my list so far (I ain't dead yet!). I'd like to say "in no particular order", but we all know that's not possible with me...
8. Michigan (Upper and Lower peninsulas)
10. West Virginia +
11. Kentucky +
19. Rhode Island
22. New York
24. New Mexico
30. North Carolina
*official resident at one time or another
+ pretty sure, on a childhood vacation
Sorry, District of Columbia. Not all of these were for any extended stays or even overnights. I'm pretty Oklahoma was just as we drove through on a grad-school spring break, but I'll still count it.
Feel free to write your states or totals in the comments.
