I like to travel by public transportation because this is the best way to observe the things around you. I can see lots of people and their activities while traveling. For example, some travelers may be listening to music, some might be reading the newspaper, and lastly, some will be interacting. If I am sitting in the window seat, I am happy because I can see things along the way. This excellent sightseeing. There is a saying, "The more you travel, the more you explore."
