Challenge the nearby gym
From Create Your Own Story
YOU MADE THE RIGHT CHOICE! You know your Pokemon games because you cannot advance past Route 20 until you beat the gym. The problem with this though is that you cannot fly anymore until you beat a certain gym and you can only fly to towns that you have previously been to starting now! You run towards the gym hoping to beat them. You find the gym and realize that it is just a school and is a normal type gym. What will you do?
