Tony commented that if we do not have the travelers in time to support the inspections, that we should go ahead anyway with the inspections - and "back fill" travelers as they become available. That being said , it is much preferred to have all the travelers
prior to inspection , so we will need to do our best to back fill the travelers if needed </div>
