One of the best ways to learn new information or refine information you already have, is to see what others are doing/have done and figure out how to incorporate lessons learned by others (ie: skipping the "school of hard knocks" approach) into your everyday preps. Alpha Rubicon has been a well-respected survivalist site for a number of years, which is why this weekend's assignment is to read all of the articles on this page http://www.alpharubicon.com/prepinfo/prepinfo.htm. Doing this should significantly increase your knowledge and preparedness skills.
Like all sources of information, no matter who is providing it, you have to use common sense and use the parts that work for you. As is always the case, some information will be spot on, much will be somewhat useful and/or interesting, and some will be totally useless for your purposes so take care in choosing the things that will work best for you.
