Which way is the wind coming from when you smell it? srs question. There are only 4 or 5 locations close by that can generate any smell, the tanning factory, orica or further down towards boundry road.
The tanning is south/east, boundry road sth, and orica east.. there is nothing to the North/West that would generate a smell, and the wind rarely would come from the east.
The tanning factory is the worst of these smells, and if you use the ring road frequently, you will smell it quite often.
