I remember when 'preppers' were considered the fringe paranoid nutcases, and it sucks that that is now referred to as 'back in the day.'
I keep loading up on supplies, Whole Foods, Costco, and deliveries from Amazon and Walmart and others...
I have over $8K in cash, $1, $5, $10, $20, and $50's no $100's. You can't expect receiving change when trying to get things going or when you're in a hurry to go somewhere
