I've been impressed that the show will post a correction to what someone has said if it is factually incorrect. I have had two things catch my eye, which didn't seem .

On one of the most recent shows, the person was taking about inflation of 1300%, so it would cost 1300 times more. This is not correct, it would have been 13 times more. OK, this is still a lot, but he was off by a factor of 100. The show did not catch this.

Another thing the "expert assessor" did not comment on was the firefighter in NY. He indicated his air tank held 45 minutes and his food cache was 20 minutes away. This gave him just enough time to get to his cache, have 5 minutes, then get back. He didn't give himself any extra time. He was just perfect. In fact, during his test run, they said he made it under 45 minutes. I have a feeling it was just under, otherwise they might have highlighted the fact he did it in "35 minutes or 40 minutes"...
Two problems
#1: In a real situation, he would probably be breathing heavier, thus consuming more air and reducing his tank level.
#2: What if he is delayed by someone in the street...

Solution: Carry a second tank or have his cache closer to home.

Perhaps I'm naive to the nuclear power plant, but even if it did not power plant itself and was in fact by diesel generators, I'd really like to think the people planning would have more than enough diesel, plus lots of extra, to have a controlled shut-down.

I've always defined Prejudice as "prejudging someone". One of the Merriam Webster definitions of Prejudice is
a (1) : preconceived judgment or opinion

By definition, is Affirmative Action in fact a prejudice? It is based on skin color, nothing more. It doesn't take into account how much money the person has in the bank. It doesn't take into account if the person has a 4.0 GPA or never graduated from elementary school. Personally, I am surprised minorities are not offended at the idea they are collectively grouped together as either poor and/or uneducated.

I think there are groups of people in the country that take advantage of this and they should be ashamed of themselves. Think of all of the people/refugees who have come to this country legally/invited in the past 30-40 years from war torn countries/political strife with nothing more than the clothes on their back, not a penny to their name and an entirely different language. Many are now business owners or have taken up a trade and made a name for themselves!

I've been enjoying the show and look forward to each Tuesday to glean some information each time. Some of the ideas are not realistic, but someof these ideas aren't that crazy...Look at Hurricane Katrina, Mount Pinatubo, the Volcanic dust cloud over Europe disrupting air travel. Also, if you noticed some of the filler material for the guy in LA segment talking about the riots...Doesn't seem so far-fetched!

I, for one, am a closet prepper. The most likely concern is a big earthquake in California. I do not have the monetary or time resources some of these people have -- 7+ hours a day! Wow! The very first people they shows building up a fortress made out of shipping containers --- these people ARE ALREADY living in a post apocalyptic world!

My plan after watching this show is to begin building up more water and rice. I have been acquiring some freeze dried food in the 10# containers. With a 30 year shelf life, I figure it is a good investment! I already have seven 20# bottles of propane. Yeah, not too much, but it is a start! Water is next ... start buying the 6 packs of 1 gallon jugs. I'm not looking for a long-haul, end of the world stuff, but prepping to be able to survive for at least 1 month is prudent for anyone!

My wife and I have also considered the purchase of a shotgun and perhaps a small arm.

NatGeo --- if you read this --- perhaps a few stories on "real people" planning for less cataclysmic scenarios, such as getting caught in the snow for a few days, an earthquake, hurricane, tornado...
