Next Friday, May 4 is the second annual GenTX Day, when students across the state spend the day surrounded by people wearing college t-shirts.  You’ll see college t-shirts at the office and at stores and restaurants, and even teachers and staff at schools will trade the business casual clothes for big bold letters and mascot faces, all to support life after high school.  All who wear the gear will be sending the message that a college education is a good investment.  How does it work?
