DENVER — At a weekly meeting in the country’s oldest Veterans of Foreign Wars post, a Marine began by asking members to close their eyes and inhale.

“Bring your hands to your heart center,” he said. “Notice all the air that is moving around you.”

It was Tuesday at V.F.W. Post 1: yoga night. Wednesday is meditation. Friday is photography class — unless it is open gallery night, when hundreds of civilians peruse veteran artwork while a D.J. spins records. The post hosts a monthly film series. And meetings often have as many backward ball caps as V.F.W. hats.

Do not come expecting a bar. There is none.
