Valero Texas Open - Thursday brings the PGA TOUR's Valero Texas Open to TPC San Antonio in San Antonio, one of the biggest golf weeks in Texas. Watch pros tee off across the course, soak up the sunshine and enjoy the buzz of a big outdoor sporting event. It's a great pick for golf fans and families alike, since children 15 and under get free general admission with a ticketed adult. Military and first responders also get free admission.
