highly dispersed population. Likely help in Houston and Dallas can be quick but places like San Angelo and smaller towns may well be on their own. There are lots of major military installations like Fts Hood and Bliss and numerous major Air Force bases that have troops, equipment and facilities that could help if they were allowed. If they actually were doing rolling blackouts of cycling 4 hour durations they could make it work along with asking folks with power to absolutely minimize usage, but they don't seem to have the technical ability, will, organization or know how to do that.
Beto had it right last night on CNN when he said when it comes to planning and dealing with natural disasters, TX is a failed state. If anyone wants to see what laissez faire local politics looks like, this is a good example. Low taxes do equal low level of services. Similar things of even bigger and longer import are happening in GA, LA and other states where the states are allowing rural hospitals to fail and close and the closest emergency room is no longer 25 miles away, it is now 100 or more miles away. I hope those areas have life flight helicopters and your insurance pays for that $30k trip to the ED when you have that accident or heart attack.
