Six months of expenses. Rent, car, insurance, electric, internet, and food for us and the dog. Plus a little buffer just in case. Probably a bit excessive; but I’d rather have it sitting accessible in case of an emergency rather than in a bank that’s basically paying the same amount of interest. I figured this way we’re covered for a bit in the event of a banking failure, or in case the next Weather Baroon has an emp device attached.
