Thanks for the review :D
When I tried to imagine myself in Oreburgh, the first thing which came to mind was the coal mine and I suddenly realized that the air around there would most likely be polluted which is why I added it. Then I considered the people of Oreburgh stupid for doing something which was harming them, but then I realized just how cold it would get in Snowpoint (especially in the winter) and that sorta went from there.
As for the test, my original idea was to have him deliver a pokémon to somebody in the mines, or some kind of battle, but then I realized that a trainer's licence would be needed in any job which required more than two pokémon, so I thought of it more like a driver's licence. As for the last question, yeah, it was a little anti-climatic, but I needed a way to mention that law because it might actually become important down the line. Red Herrings are the best fish.
