I have a Daughter who was born on Pi day. When she was little. she would tell you it's the second most important day, right after Christmas. Pi Day actually became a school wide fun day because of her, (small rural schools can be fun that way). We would bring a couple of pies for her math class to celebrate. Oddly, she much prefers a strawberry cheese cake for her birthday over pies.
I suspect she will NOT allow the change...........
But not for Pi Day. Having taught classrooms how to calculate Pi by tossing "frozen hot dgos" and literally timing the period of the swing of an apple pie suspended from the ceiling, it's pies or nothing!
