You’ll find it a big help if everything you take with you on your camps and travels has its place. You never know when, or under what conditions (dead of night, emergency etc) you’ll need to access that all-important ‘thing’ – be it a torch, lighter, toilet paper, keys, kids dummy, kids (I’m guilty of that one) etc.
Your campsite, or car / caravan is so much smaller than your house – but it’s all somewhat new and different. Knowing where stuff is prevents raised voices, the blame game and stress (on all sides). I used to instruct my cadets on this and their need to put their hands on their toothbrush without pulling the whole kit apart.
