Yes, that is how I judge the level of tourist. The amount of vans I see out driving around is a sure sign.

During covid I lived in Astra condo on Changklan Rd. When I would go to the elevator I had an awesome view looking North. There was a a water retention pond that was across the way that had a tree lined gravel road running along side of it. The dormant vans would line up and park in the shade spots. There were dozens of them. I felt bad for them because it was like that every day for months. Also from that vantage point you could really get a good view of the hanging smoke. Just awful. At ground level you often don't realize how thick it is. Although one day while walking down Loi Kroh Rd. the smoke was rolling down the street like San Fran fog !
