You should start with an information packet, that does make some mention of the scavenger hunt. It can be a good way to get to know some of the locations around town. For a quarter, Thurman will give you a tour in his carriage.

There are some activities such as these two that are completely automated and do not require another player to do. But I would say that you will get the most out of the game by interacting with other players.
