President Barack Obama made a surprise visit to the troops in Afghanistan to thank them for their service. Their sacrifice to keep this country, The United States of America, safe is certainly unmatched. Though there have been attempts made by other countries to cause us harm, we have not had to deal with the devastation that is seen in a lot of countries. Thanks first of all to God but also to the people who sacrifice their lives daily to keep us safe. Have a safe and HAPPY MEMORIAL DAY!
