If you are available on May 4th from 6-9 pm you'll want to head to the Amphitheater in Sienna. Its Cinco time you'll get to hear some great music while eating some Latin-inspired food from some hightly rated food trucks. Bring your chairs, balankets and beverages for this fun & relaxed night with your neighbors. If you are new to Texas, Cinco De Mayo celebrates the Mexican army's victory over France in 1862 during the Mexican War. Yes, lots of Texans use this as an excuse to drink Margaritas, but there really is something to celebrate here!
