As you have discovered, you are now past most of the major steps in kicking off a great camping experience. Once you have settled on the location of your car, tent, and campfire, all you have to do is unload other tools that will be required during the camping period. This may include food coolers, chairs, tables and other relevant materials.
My advice is that you use a plastic container to store everything. You can use plastic containers to store cooking supplies, safety kits, clothing, and start-up equipment. When you have all your things in the right places, it will be easier to keep track of everything you need. You can also tie a rope between trees and use it to hang your shoes or other things that you do not want to see lying idle. This is a smart way of ensuring that you remain organized and save yourself from any pain or suffering. This will also keep your campsite clean and safe.
