I like to travel by a public transportation , because this is best way to observe the things around you. I can see lots of people and their activities at the time of travelling, like some travellers may be listening to music , some might be reading newspaper and above all some will be interacting . If Iam sitting near window , I feel so happy that I could see the things on my way. This is really a good sight seeing .There is a saying "More you travel the more you explore."
