I buttume you're referring to simply walking away from the affected area.
This question is no different in concept that the one that usually pops up for people attempting to hike the Appalachian Trail; and there's a web site devoted to the trail and to through-hikers which provides plenty of information on preparation, provisions, etc.

It was silly to keep hearing that reference "poor, therefore no means to get out". Of course you have a means to get out, unless you're not able-bodied or otherwise burdened! You have 2 legs and more than a day from the time of the first orders to get going. Given the speed the cars were not moving (and the numerous options open for travel routes, not open to cars), you'd probably have been better off, than sitting and waiting to get flooded over while stuck on the freeway. For the poor, the question is moot. 24 hours is enough time to do a good 50 miles, particularly when your life is on the line, and I've done as much as 70 in that time period; and nearly 45 on another occasion (20 hours) with plenty of time to spare to see a 3 hour movie, eat breakfast, lunch, dinner and an evening snack out, explore the landscape, ford a river, and rest in a couple parks while enjoying the scenery even with a sprained or broken ankle for about 15-20 miles of the trip.
