There is an army of veterans who are also artists. Those living in Macomb and Oakland counties are being invited to take part in the Detroit Institute of Arts Tour and Workshop for Veterans, happening Sept. 14 and 21. "We found out how many veteran artists there were when we decided to put on a show," said William Schranz of Harrison Township, an artist and United States Navy veteran who is corralling veterans from Macomb County to attend the event.
