Since my previous Supernatural map has proved to be popular, here is another one.
This one includes all of the known locations where the Winchesters travelled, and how many episodes took place in each state. It doesn’t include locations that are just mentioned or shown in flashbacks because it is from the data I collected in tracking the Impala. (I was also too lazy to add Scotland to the map, for that one dot.)
Again, click the source link to embiggen.
P.S. Maybe they avoid the South because it’s too hard to find Canadians who can do believable Southern accents?
