Once you've got your own bags sorted, you need to start thinking about bug out packs for those people in your group who might not be able to pack their own gear. This primarily includes the very young and the very old, and proper preparations for these two groups is essential if you are to have any hope of moving safely from place to place with speed.
Many survival debates have focused over whether to make children fully aware of why they need to have bug out packs ready to go at a moment's notice. On the one hand, many children like to know exactly what's going on, and it may be easier to motivate them to keep quiet and move quickly if they understand the seriousness of the situation.
On the flip side, they will quickly lose their childhood innocence if they believe they could be under attack at any time which may cause them to flip out when the apocalypse comes. At the end of the day, it will depend on your kids.
In terms of bug out bags, you should sit with your child to pack away the following essentials:
You will also need to think about bug out packs for any elderly members of your survival party. The two key reminders here are warmth and mobility. Hypothermia will be a real risk to the elderly if all power is lost, so you need to pack plenty of thermal underwear and thick fleeces for them. Microfiber clothes will pack up pretty small and are reasonably lightweight too.
In terms of mobility, make sure that any walking aids can be broken down quickly and easily to save space, and that if they require a walker with wheels that someone in your party has a puncture repair kit.
In an ideal survival situation, everyone will be able to carry all of their own equipment. However, if you are travelling with children and/or the elderly, their bug out packs will need to be much smaller and lighter than everyone else's so that they can keep up with the pack. This will mean that the rest of their equipment and provisions will need to be carried in other people's packs.
Make sure that you discuss this with the rest of the party before handing out the additional equipment and come to an agreement as to who will shoulder the extra weight.
