In the instructions to appointees booklet it lists required and recommended items to bring on I-day. At the bottom of the page, it says to hand carry these items, do not leave them in your luggage. I only have one piece of luggage, my backpack, with everything in it. I understand that it will be carried in my left hand on I-day. But, should I bring another smaller bag to carry my needed items? Will our backpacks be taken, or just our phones and civies? Please help, very confused. Thanks.
