Why, you ask? Because Mojo is able to channel all the awesome power of the Universe and cause Karma to bite you in the most sensitive of places, THAT's why!
One of Mojo's peculiar little quirks is, there are some towns she does not like to drive through. As in, most of 'em. So often when she goes home she will take an oddly roundabout route, to improve her ratio of trees to buildings along her drive--meaning, the more trees and less buildings, the better.
