Yes, yes, of course it is Valentine's Day, everyone knows that. This day is also shared by a lesser-known holiday in the U.S., National Ferris Wheel Day, established to honor George Washington Gale Ferris, the engineer who created the wheel named after him. If you haven't read Erik Larson's engrossing 2003 historical novel Devil in the White City about the 1893 World's Fair and serial killer H.H. Holmes, pick it up. Ferris provides one of the more interesting characters in it, having been recruited to design and build the first Ferris wheel for that World's Fair in Chicago in order to show the French who was boss now after they'd built the Eiffel Tower for the World's Fair held in Paris several years before.
Since Ferris Wheel Day and Valentine's Day are both observed on February 14, it's pretty easy to knock out both birds with one stone by taking a romantic ride on a Ferris wheel. Done. Both observed.
