In Chiang Mai in a month or so we'll be wishing for this type of pollution now being experienced in Bangkok.. It's much worse than what's going on in Bangkok now. Buses and traffic in general are being blamed for it now but from the fire map it looks like the whole of Cambodia and areas around Bkk are on fire. And don't forget the thousands of factories in the city as well. It's a wonder how that filthy dump is not shrouded in this type of aerial muck 365 days a year.
