One day, I'm driving in to school in Boston. I know how to get to my destination, but not much else (before GPS or google maps). My path is blocked but no detour is marked off. Two cops are standing beside the detour sign having coffee. There is plenty of room to park, so I pull over and ask how to get to my destination. One guy screws up his nose in my direction, "What do I look like a tour guide? Get out of here before I have your car towed." I have not visited Boston as a tourist since.
