Make A Difference On June 11th  

This June 11, communities everywhere spring into action.

  • A photo album sits on many shelves, filled with memories of faithful companions no longer here. Others plant trees - maple saplings reach skyward as living tributes to beloved pets. Time helps, yet sharing these memories lightens the heart.
  • Now's the peak season for sweet corn and farm-fresh vegetables. Local growers (check the stands on Oak Street) offer better taste than any supermarket produce.
  • Back in old Hawaii, King Kamehameha I knew something about bringing people together. His down-to-earth leadership united the islands through practical give-and-take - a lesson worth remembering.
  • Nothing beats a spontaneous block party for getting to know the folks next door. Drag out some lawn chairs. Bring the kids. Real conversations happen naturally outside.
  • That German chocolate cake recipe from your grandmother? Perfect for sharing over the fence. During Flag Week, pass along proper handling tips while you're at it.
  • Most mornings you'll spot the regular crowd walking or biking around Palmer Park. Join in - 7am sharp. Some show up for exercise, others for coffee and gossip. Either way works.
