HOUSTON -

The USO has centers at both of Houston’s airports, but their headquarters is what some consider the city’s third airport.

Ellington Field is home to thousands of troops representing all five branches of the military.

The Coast Guard’s Craig Potts works hand-in-hand with the USO on a daily basis.

“They help us out so much to bring morale to the troops here in Houston with all the events that go on here,” said Command Master Chief Craig Potts, with the Coast Guard Air Station in Houston.

The USO sets up big events with Houston’s professional sports teams.

On Memorial Day, the Coast Guard will take the field at an Astros game.

“I’m a huge baseball fan,” said Coast Guard rescue swimmer Michael Vicchiariello. “It’s pretty neat to go out onto a major league field.”

The USO also makes spontaneous stops at the Coast Guard hanger to donate meals, and sometimes, even Girl Scout cookies.

After 30 years in the military, Master Chief Potts is retiring. He said he will miss his time with the Coast Guard, but admitted he will also miss the USO.

“It's a great thing. We're going to miss it,” said Potts. “It means a lot to everybody my kids, my wife, myself and the men and women in the service.”
