I'm never quite sure what constitutes having been to a state...staying there for a day or more? Staying overnight on a drive through? Stopping for 30+ minutes? Driving through?
I've been to 8 states if you count staying there for at least a day/sightseeing, etc.

15 states if you count driving through or layovers on the way to other places/staying overnight. I'm not sure about Tennessee; it's not the most direct route, but I'm guessing we've gone through there to get to Illinois at least once.
