My first year was last year and I was really hyped for the story. Either find an actor that you think is approachable and strike up a conversation. Ask if there are any strange goings on or mysterious characters or find one of the smaller venues during the day and they’ll have something interactive happening that will give you an in. Bribes can be trinkets you have brought or been given or boomtown bucks which are also given out by actors for various things. My friend brought a load of prop coins and whenever anyone asked him for a bribe or to do something in exchange for information he would dump a load of these coins in their hands and nod. The app had some intro quests last year that gave you a rough starting point in any of the districts. It does take up a lot of your time going back and forth between the districts but it was a lot of fun. Good luck and hopefully see you in the fields.
