Rebel buffalo: For ages we've traversed. West to east and back again.

Follower buffalo: Everyone does it.

Rebel buffalo: Maybe there's another way. I'm going down this time. North to south.

Follower buffalo: What will the herd think?

Rebel buffalo: No comment. The east coast is nice, the west cost is nice but there's just a vast expanse of nothing in the middle.

Follower buffalo: But if you go down from top to bottom, that vast expanse of nothing goes on even longer.

Rebel buffalo: Think of it this way. If you follow the coast all the way, the good bits last the whole journey.
