How Deep In Pi Is Your Birthdate?

I baked a tart and took it to New York, Atlanta, St. Louis, and Los Angeles, because my math teacher said to take pi to 4 dismal places.... :D
All I`ve seen on the Tulsa news this morning is about bakeries and diff. kinds and sizes of "pies".
Guess we Okies travel to the beat of a diff. drum !! "HOT CHERRY AND APPLE , WITH VANILLA ICE CREAMARE MY FAVORITES !" AHAHAJAJAJAHAHAHA
