There is no reason for a civilian to go out AT ALL in that situation until an “all clear” is given.
Only conceivable exception would be for a medical emergency that is life-threatening.
Agreed...just saying what I did on 9/11..well after the attacks occured...And I only went a block to get milk, bread and toilet paper from the Daggies! So yeah..wait it out, but when it is clear, go in a group as I said...and get nothing that isn’t essential or that you can’t drop in a hurry if TSHTF again.
