Make A Difference On March 31st  

March 31st connects several great causes - some might surprise you.

  • Many don't realize their local area holds rich transgender history. Dig into these stories, then amplify trans voices and achievements on your preferred social platform. While you're updating online, take a quick inventory of those scattered photos and documents. A secure backup prevents future headaches.
  • At the market, think of Cesar Chavez. His fight for worker rights lives on through fair-trade choices - just check the labels on your produce.
  • Local teachers mentioned their art supplies run low after winter. New crayons and drawing materials make a real difference, especially now. Speaking of passing things along, old stories carry more weight than we think. Pull up a chair and share one that shaped you.
  • Those local potatoes at the farm stand? They beat supermarket fare any day. Get creative with recipes - no rules apply.
  • Between tasks, clean up computer files and update a password or two. Simple fixes prevent bigger problems.
  • The LGBTQ+ groups around here could use a hand. Stop by, volunteer, donate - whatever works for you.

March 31st - Notable Birthdays

  • Back in 1962, Cesar Chavez took up the fight for farm workers' basic rights. His grape boycotts proved that peaceful protest worked, leading to safer conditions and strict rules about pesticides. By the time of his death in 1993, his achievements had earned him the Presidential Medal of Freedom.
