One day when i was driving home , it was around 9:00 p.m and the road was deserted. There was huge bend and the place was pitch dark. There was no street ligts and the there was no other building near by. Suddenly i saw white cloud of smoke arising and the smoke like effect was coming out of big pipe placed near the road. I went very close to pipe and saw why there was a big smoke arising out of the pipe. Later to my suprise i discovered that it was dog which was kicking up the sand.
