Yep, so far the worst experiences from friends/family have been the ones that tried to evac.
Our best friend had Austin City Limit's tickets, (huge music festival), for this weekend, so she decided to take off early, and take her cats with her. She left here at 6am. She didn't get to where she was staying in Austin until about 2:30am. She took about 2hrs out in columbus around 8pm at her parent's to eat and de-stress a bit from riding all day in a hot car with two pissed off, hot cats. Even subtracting those two hours it took her about 18hrs to make a trip that would normally take 3. It also ate up nearly an entire tank of gas, when it normally takes half a tank.
My parents left at 5am Thursday morning. At 9am, when they called me they'd only made it about 5 miles. I called them back at 11am, and they'd only made it a couple more miles. When I checked in at 8pm, they'd made it to Sealy, which is an outlying suburb. At 11pm, they'd made it to the far side of San Antonio and had finally been able to gas up the vehicles, and eat. This should normally be about a 3.5 hour trip.
Blech.
All in all, sticking here to babysit tanks, with my father in law, and wife, with a ton of water, 90+ gallons at our house alone, a ton of food, a small generator, lots of batteries, with a dozen friends in the neighborhood at another place that is a huge concrete cube, with enough water for everyone for over a week seemed like a much better idea than trying to evac.
BUT...That's because we live in a neighborhood that's high-ground. And we all have a lot of practice working together and preparing for living without electricity for weeks at a time.
