I'm in NW Louisiana right now, since my plans to return home via SE Louisiana were foiled by Hurricane Ida. Parts of US 190 I wanted to clinch between Baton Rouge and Covington were still closed by flooding or downed power lines, last I checked.
Yesterday evening, on my way to Shreveport, I drove US 167 to Alexandria. That took me past the huge emergency "megashelter" along US 167 south of Alexandria, built after Hurricane Katrina to house large numbers of evacuees (especially those with medical or other special needs) from future hurricanes. The parking lots were full of buses, and some private vehicles. Looks like a lot of evacuees are staying put for now (as advised by the governor), and holding off on trying to return to their homes in SE Louisiana.
