Randall, the Personal Finance group hasn't been talking a lot about alternative currencies but I do know that retirees will have to figure out what services or goods to trade if the federal currency collapses. It may be even more difficult for us than for young people. We're all in this together. You may want to check out the Economic Evolution group which was started by the founders of the Fourth Corner Exchange.
Welcome, Randall! With your background you may be interested in our Personal Finance group. Use the Groups button at the top of the page. There are an overwhelming number of groups but also a handy search box on the upper left of the Groups page. Our group is just starting but we have a number of discussions going to explore local loans, local banks, local investment, etc. We are aware of the potential for currency collapse and interested in pursuing options for that as well. Hope to see you on the group. Judith
