Many hardcore preppers I have talked to recently are very glad they have started prepping years ago. Recently I did a video on night vision and a few people that have been putting purchasing it off went ahead and purchased it. They said they are glad they did it. Now they need to practice with it and get to know it inside and out. PRACTICE walking around with your NODS. IF you do not have NODS practice walking in your AO in the dark. Be careful and do not hurt yourself.
