When I was a child, Memorial Day meant the start of summer. Now I'm an adult and it means so much more to me. Take a moment this weekend to reflect on the meaning of Memorial Day. Remember that the freedoms we enjoy this weekend, and all year long, to swim, to gather, to have outdoor concerts, to hike in the national parks, came at a cost. At the start of summer we should always recall those who gave their lives, the "last full measure of devotion" to keep us free.
