This week, Iowa Public Radio has been taking a look at what it means to be a military veteran in the state. Today, Rob Dillard examines the mental problems that sometimes beset veterans after they serve their country. Many turn to booze and drugs to fight off the demons that haunt their dreams after fighting during wartime. Thousands of them wind up on the streets or in homeless camps after they fail to reconnect with family and friends. Rob sees what’s being done in Iowa to help these troubled veterans.
