Their has always been plague in the 4 corners area, all 4 states see the plague on a cyclic basis. If that one doctor practices in Colorado long enough this won't be the last case of the plague she sees. Normally the Prairie Dogs are the ones who carry it, they seem to go dormant for years and then their will be an out break. Usually the Indians, mainly remote living Navahos, are the ones who come down with it.
Correction on post 15, “and then their” should actually read “and then there”.
Oops-should have read all the posts....bad here.
