Welcome to the largest city in Johto, Goldenrod city. You can see the radio tower from here. there are also some supply shops here as well as the departement store, and a game corner. if you're ready (4 badges) you can use the bullet train to get to Kanto. the Gym leader here is whitney, and she uses normal type pokemon. But don't look down on here, theyre tougher than the other two gym leaders pokemon, so keep a firm advance.
