Look no further, a little further behind USJ, there's this plot of land called Bukit Kemuning/Kota Kemuning which is infamous for its open burning. Every night you can see a super thick smoke that covers the area and extends to my housing estate of Taman Klang Jaya/Sentosa/Andalas. And you can clearly see the source of smoke, peat fires and open forest clearing just as you drive along KESAS. Its been going on for months.
