The Lower Westside is an ideal place to live because it's close to the shore.
The world famous Vermillion City Gym. It's located on a freestanding structure. The Golden Ball is divided into three levels. First level is the gym, second level is a restaurant with a view of the gym, so every Pokemon trainer who battles here must be confident because there are usually a lot of people watching, and the third level is an observatory. Lt. Surge is the Pokemon Gym Leader of Vermillion and he specializes in Electric Pokemon. People should avoid battling on days with thunderstorms because this tower attracts lightning and it makes his Pokemon a lot stronger.
