Most of the people who lives in the immediate neighborhoods left their stranded vehicles and walked home.
Most of the stranded people I met a few hours later (9 PM ~ 11 PM) who were still staying with their vehicles were from distant cities 10 ~ 30 miles away. All of them waiting for a ride home, impossible for some because the water in the streets was still 1.5 ft. deep in low areas.
Some of those people just needed a jump start of their dead vehicle, I jump started several vehicles successfully but some cars were beyond hope and needed to be towed.
I talked with a couple that had one of those cars that was beyond hope, the fellow told me that his wife/lady friend tried to come and pick him up but only got as close as 2 miles away and she walked to where he was. It was probably around 11 PM and they decided to walk the 2 miles back to her car she left in a parking lot.
I told them to hop in to my vehicle and I'd give them a ride as far as I could, cutting through the neighborhoods and avoiding the main arteries we eventually got to her car, I dropped them off wished them luck and headed for home.
Here's one thing I noticed right away when a disaster like this happens, the "Rule of Law" and respect of property is immediately thrown out the window, e.g. there were, at times, a line of cars & pickup trucks (mostly pickup trucks) driving across ALL of the lawns and yards to avoid the flooded street. There were some who were so caught up in the "apocalypse" decided that because he was giving "aid" to others that he could park his car right in the middle of my lawn, never mind the fact that my perfectly good driveway had enough room to park 4 cars...
I'm glad that that was the only "mob rule" incidents I saw, as minor as it was, there's a grain of truth in those apocalypse type movie of how desperate people behave, it's all for them and none for you... Interesting observations to be sure.
