SAN ANTONIO - First Lady Michelle Obama will be making a trip to San Antonio this week to encourage our young and talented students to pursue a college education. Mrs. Obama will speak at the University of Texas San Antonio for the 4th Annual College Signing Day event on Friday, April 28, at 10 a.m. in the Convocation Center. She is expected to talk about the importance of getting a college degree. The event is the culmination of 'Destination College' - a week dedicated to students' commitment to higher education. Her office says she will 'highlight the significance of pursuing and completing some form of higher education, and the importance of students doing their part of answer the President's 'North Star' education goal.' That goal calls for the U.S. to have the highest percentage of college graduates in the world by 2020. Mrs. Obama will also encourage Americans to wear 'college apparel' on Friday to show their support for higher education. The first lady will also support Mayor Castro's efforts to 'celebrate San Antonio as both a college town, and a college-going town.' As in previous years, San Antonians are encouraged to promote College Week by wearing their alma mater's shirts and hats this Friday and posting their pictures on social media using the hashtag #ReachHigher.
