Geocache Description:


You are cordially (and circularly) invited to celebrate Tau Day: the holiday that goes all the way around the circle.

On June 28, the mathematically enlightened gather to honor τ (tau), the constant that boldly declares, “Why stop at π when you can have twice as much fun?”

Tau, for the uninitiated, is the ratio of a circle’s circumference to its radius, sometimes denoted , approximately 6.28, and beloved by those who believe math should come with clearer formulas and larger desserts.

Some say Tau is the superior constant. Some say it’s a revolution. We say any excuse to eat more pie is a good excuse.

So join us as we celebrate the only holiday that encourages you to: Eat. Twice. The. Pie. (We don’t make the rules. Tau does.)

Bring your appetite, your sense of humor, and your willingness to debate geometry over dessert.

Event starts at 6:28 pm.  (Notice a pattern here?)  Feel free to come earlier if you want to grab a meal.
