Now is the time to assess what you have. Now is the time to make goals for the next six months. What would you like to add? Now is the time to look through things like a 72 hour kit and update items (like clothes sizes and perhaps the type of clothes. Change to cooler clothes now, warmer clothes in October--assuming you are in the Norther Hemisphere).
If you are having a hard time deciding how to track your emergency items, I have been working on a plan and will share that with you later this month!
