If you want to experience real camper, matches for your campfire. Old newspapers to help get going and lighter fluid are necessary. Keep flashlights and extra batteries in your vehicle in for emergency light. But leave them to get the full effect of camping.
Take homemade materials such as oatmeal and aspirin for bee stings and bug bites. Bring rope; you never know when you might need. Other essentials include toilet paper, homemade bug repellant, sunscreen, and an ax for wood chopping.
