[sustran] Re: On Noise Pollution

[Walter Hook]

in delhi and some other indian cities, trucks are not allowed to enter the 
city center until the night time to reduce congestion during the day.  The 
result is that the trucks come rumbling into urban streets at night making 
an earthshaking racket.  This really makes sleep difficult if you live on 
any major road.
