Everyone knows about carbon monoxide ..deadly , invisible , tasteless, odorless and the cause of many respiratory diseases and ailments..including death and if you survived death then ...permenent brain damage.
However on cold windless nights that gas wants to turn into a liquid. Tonight in Saskatoon it should be close to -40 degrees below zero C and relativly windless. This is a great opportunity to see the dome of stupidity. Set youself 10 kms away from the city and in the wee hours of the morning you'll get to see the once a year event. Lights from the city will illuminate the carbon monoxide that hovers over the city while people sleep quietly in their heated homes.
