The Miles Howard Hotel was the Greyhound Bus depot for Miles City. During my brief time delivering the Great Falls Tribune to the (very few) subscribers in Miles City, I picked up my load there every afternoon. The picture of me getting Gene Autry's autograph, posted here somewhere, was taken in the lobby.
The MDU powerplant was on the south side of Bridge between 7th and 10th, closer to 7th. I think the cross street on the postcard is 8th. The building at the right edge was the Miles City Steam Laundry, which used steam from the plant, and was still standing in June. You can see a representation of rail cars behind the building. Strangely my clear memory is that the stack was at the other end of the building, so it goes.
The Milligan Hotel sign still makes my teeth hurt. A dentist who shall remain nameless, although I am afraid I may remember it, had his office with the peddle-powered grinder/drill, well maybe I'm not quite THAT old, on the 6th street side of the Milligan. When I visit I still can't even walk along that block.
