Look at India. My sister had tried to "tour" India once. She ventured outside of the Hotel, and immediately there were massive # of cows, people, lots of other animals, and all of their poo everywhere, there were no way to walk.
So, the whole time she just stood and waited for the tour bus; the tour bus then struggled between all of the living being and their poo, ....... the whole trip, no matter where she went.
