Thank you for posting all this.
My parents lived in Coleman for some time, and it's an interesting place. But, like many coal communities, it's also plagued with illness and people dying at an early age be it mining incidents or related diseases. We were having supper there once and the number of people towing O2 tanks into the restaurant shocked me.
When Canmore was exploding the Pass area got very excited that Calgarians were going to come in droves and pay $500K and more for anything they could get their hands on. Never happened. Cranbrook thought the same thing - Calgarians would buy everything so they could access Fernie.
