North Texas Patriot Guard Riders will establish a flag line at the Waldo Funeral home and receive the family and friends of William Matetzschk. The flag line will be established before visitation and will continue until after the funeral service starts. After the beginning of the service, the flags will be furled and stowed in the flag bike and riders will then be dismissed. The North Texas Patriot Guard Riders have been invited to attend the funeral services.
