Finch’s rules are that there are no rules, since life already has too many. Instead, there are guidelines: he and Violet have to use real maps, not their phones, to find places. They’ll alternate choosing where they go and might also just see what they can find, but they can’t go anywhere ordinary. And at each site, they have to leave something to prove that they were there.
Laying down these ground rules in addition to Mr. Black’s guidelines allows Finch and Violet to better dictate how they want this project to play out. Especially when Finch insists that they can’t go anywhere ordinary, it suggests that he wants them to find the beauty in the mundane sights around Indiana.
