Yes, I really did keep track of every location in every episode and calculate the mileage.
Some locations are completely unknown, and therefore not plotted on the map. If I knew the state, but not the location within the state, I used the city closest to the geographic center of the state.
Note: this is just where the Impala went. That’s why Season 7 is so short and it doesn’t show their trip to Scotland in season 6.

The two dots in Oregon though… one for sure is wrong. Grants Pass, from season 6, is entirely in the wrong place. It’s much further south.
