They are oil sands damn you. Hard bitumen not oozing tar! Manitoba only has one oil field and it is a tradition drilling operation. Saskatchewan does have a good sized patch of oil sands.
You can't be a hillbilly if there are no hills.
Winnipeg and Regina are shit stains of cities with massive problems with native gangs and endemic poverty on the reservations within their borders. Nothing good happening in them. Saskatoon is ok but small and boring. Outside of those three cities it's mostly wheat fields and the smell of pig shit.
