Shoes to fill…
Take a moment today to reflect and understand in the deepest sense that freedom is a privilege. We are privileged to speak our minds, share our beliefs, and pursue happiness because of those who have stood before us. 1.2 million pairs of shoes to fill. Exercise your freedoms with love and respect for these heroes, and join the rest of our country as we honor their sacrifices at 3 PM, wherever you are.
