Yup, 6 total including ours that I know of, plus the two or three on the Ford lot at the moment. There are two blue, one grey, one black, and at least one other white. I've personally met the owners of the grey, black, and white ones, haven't met the owners of the blue STs. None of the other owners that I've met are 'vehicle enthusiasts' per se, so no local ST club haha.
If Drumheller is your hometown, you probably know my wife's family (the Samuels), as they've been around here for several generations.
