The term "pi" (3.1415) has an unofficial day, they celebrated pi day in 1915, and I hope someone will remember it the next time. This coming Saturday is the last time it comes around for another hundred years. Our son and his family have invited us all over for PIE day (the eating kind). We don't need much of an excuse to get together and have a great time. We're all bringing our favorite pie. Speaking of March 14th, I checked, and found that there was a lot of interesting stuff going on at the time of the last pi day. For one thing, the Great War aka WW1 was underway. The Dresden exploded and sunk on March 14, 1915. Serious stuff. The USA was hosting the San Francisco World's Fair during 1915, from February through December. I found an interesting article about the Top Ten attractions in San Francisco. Here's the link.
I hope you enjoy the article as much as I did. I do feel that such an undertaking would be virtually impossible these days for a whole lot of reasons. Happy pi day!
