Bagon's locations. Everyone knows where to catch it, but I don't know if people have thought about why.

"Bagon has a dream of one day soaring in the sky. In doomed efforts to fly, this Pokémon hurls itself off cliffs. As a result of its dives, its head has grown tough and as hard as tempered steel."

It is found in two patches at the top and bottom of the same cliff. If you caught one from the patch of grass down below, it's only because that one failed to learn to fly.

What else did you notice?
