Do you keep any FRNs on hand in case of emergencies or if you need something from someone who only accepts FRNs?
Nah , not much , usually , but I have a 6k line of credit I can write checks with if I needed to , a no interest credit card with a $500 limit , the Mrs only takes cash and checks for her sewing business and she deposits that in a checking account , two other high limit credit cards that I only use for airline tickets and pay off if I use it when the statement comes , or for $50 the local travel agent will do it and let you pay cash . I can cash out silver , copper , nickel , gold at the local coin shop three days a week , lead , aluminum , steel , brass , copper at the local scrap yard five days a week etc.
