If you have parents, grandparents, or friends who are in their 80's, 90's, or 100's, they have lived through the Great Depression of the 1930's. Give them a call and ask them what it was like, how their family survived, what they remember about their friends and neighbors, what they think of today's economy, and how the economic situation today compares to the 1930's.
Don't waste any time. Give them a call today; don't wait until Thanksgiving or 'when I have time'. The time is now. If you have the ability to record the conversation, even better, and if you can videotape it, great. Pick up the phone and make a call. I guarantee you will learn a lot, more than any book.
