There was a hurricane years ago that hit Texas. They said many of the deaths were the direct cause of bumper to bumper traffic during the evacuation. Things like heat-stroke and health problems that were made worse by the conditions of sitting in traffic so long. I think the only people who should evacuate are those in mandatory evacuation zones and/or mobile homes. I was in a zone that was not evacuated during Irma so we stayed and were fine. Only lost power for a few hours. I had neighbors leave anyways and it took them days to finally get back home due to the roads being blocked and the traffic. Waste of time.
