You will do what you want. On the route you can train and prepare for the gym. There is something planned for everyone in every city. You can talk to people and look for items. You could go to the park... Just do what you want.
John-li, I asked everyone not to post in any of the threads until Monday, 9-3-12, at 6am Central time. Please delete that post. I am sorry to let you down. But I assure you that it will be worth the wait. Also, if you are EVERY unsure about what to do on it, VM me.
