Mike:
Isn't the world strange. Years ago Lionel spent thousends to create synthetic smoke for their model trains and here we are trying to eliminate it.
I read an article not long ago in a reputable magazine that inbdicated all the smoke in the western part of the country was coming from China. The stuff just drifts accross the ocean and settles on the western part of the US. Perhaps there is a downdraft in southwestern colorado due to the San Juan Mountains that is causing all the trouble in southern Durango. If we bulldoze the mountains maybe that will cure the problem. Just a thought.
