Last year, Tim Woolf, a leading preparedness expert, spoke locally. One of my neighbors went to his lecture, and I really wished I had gone when she told me what she had learned. The way I understand it, Tim Woolf was asked to see just how prepared he and his family were by living on just their food storage and preparedness items for several months, with no power, etc. They found out what they had that did not work, what did work, and what they wished they had. He is now a leading expert on preparedness.
Good news! I just found some unofficial notes from Bro. Woolf's lectures that some kind person posted on the internet. This person went to several lectures to get more complete notes. To read the notes, click on this link http://www.weshallnotfear.com/Prep.html and then click on the words "read what else Tim Woolf has to say". A Word document will open in your computer. I recommend saving it to your computer to have as a reference -- that's what I did.
I've made some mistakes over the years with my food storage and have learned from them , but if a disaster hits, it's too late to learn emergency preparedness. As the website I've linked states, "As We Prepare, We Shall Not Fear." First I'll learn about heat, as I'd rather not have my family turn into popsicles in the winter with a power outage -- that's something that I've been worried about. No longer!
