The United Nations sponsors World Maritime Day every year at the end of September. This year's official theme is protecting the environment from the impact of shipping, but I'm choosing instead to celebrate the wide variety of navigational tools that marine explorers/travelers have used. The images on my tie show a compass, a sextant, a spyglass, an astrolabe, a treasure map, and a spiked star (which may simply give directional cues when pointed to the heavens). I have a pocket-sized analog compass, but I usually consult the compass app on my cell phone for better accuracy. Today in the car I helped my 4-year old granddaughter learn about the turning circle on the app's display! She has long said that her own favorite direction is "south," mainly because that's how we travel from her house to ours.
