Visiting Boston in the 90s we were lost and looking for a museum. My girlfriend rolled down the passenger side window while we were at a light to ask the car beside us where we were. They yelled back "You're in Boston", then proceeded to have us follow them all the way to our destination.
Oh man, the best is when you pick up a rental car at the airport and dive into the tunnel and suddenly your map stops working because you're in a high-speed underground maze and you have no idea as exits fly by and you are just knuckling through it and suddenly you're out in the air and going over that huge bridge with the diagonal things and you realize that this is *not* the mass pike and so you take the first exit but it is a while and it says "cambridge street" and you think oh, I used to live in cambridge, I know where I am, and you get off the highway and realize you have no idea where you are and pull over for a breather and you look across the street and there is literally a pub called "Tavern At The End Of The World". Every single time.
We’ll, not the only reason.
