One tourist decided to enter downtown at the lower left, drive around before stopping for lunch at the intersection marked in orange, and then drive around some more before exiting in the upper right.
The tourist managed to drive through every intersection once, except for the intersections marked in yellow where he drove straight through both cross streets (north/south and east/west). What route did he end up choosing?
(Hint: He travelled the same distance before eating lunch as after eating lunch.)
