The U.S. Postal Service has slated over 200 post offices for closure in Texas, part of a system-wide move that could shutter 3,700 offices across the country. The facility in my tiny hometown is one of them. The red bits in the first map represent zip codes in Texas with post offices at risk. Named places from the U.S. Census are represented in blue in the second.
