What I learned over the holidays:

Ann Arbor, Michigan, the city in which I grew up, has become the land of the Prius.

In the mile between my father's house and the house of one of my high school best friend's, I encountered three Priuses.  Priusi.  Prius. Pri'i.

Three Prius per square mile--not to mention all the Yellow Cabs in town have gone Prius.  I think Ann Arbor's officially the Land of the Prius.
