Keeping a little bit of cash around is a great idea. Keep a ten- or twenty-dollar bill inside your wallet or purse for emergencies or situations when only cash can be used like toll booths, parking garages, etc. But what if you lost or forgot your wallet?
Add an extra layer of safety by keeping money inside your phone case. Of course, you need a phone case to pull this off, but many of us are using one to keep our cells safe from falls. Slip that cash against the back of your phone, where nobody will know but you.
Carry Beans or Rice
If you're on a long, long trek, having the right food is critical. You might think it's smart to carry things like rice or beans with you, and you're not wrong – they're packed with nutrients and protein, and they make it easy to eat healthy on the road. But the sacks they often come in aren't exactly the toughest things around.
They're liable to split and spill your food all over – inside your backpack or onto the floor. Instead, fill up plastic bottles for safer transportation of the supplies you need to stay well-fed while you're taking on nature.
Safety While Driving
Road trips aren't always comfortable, but putting your feet up on the dash is a great way to...potentially hurt yourself really, really badly. While it might take some convincing, try not to let anybody put their feet up while you're driving. If you happen to get in an accident while someone has their feet up there, it's a recipe for disaster.
Not only does the impact itself present major opportunities for injury, but the airbag might force the feet or knees back, causing possible injury to the chest or face. The possibilities are endless, and none of them are good.
Swapping Out Batteries
Having some extra batteries in your pack is a good tip at any time, especially while you're away from electrical outlets, but what do you do if you've grabbed the wrong pack and have AAA batteries instead of AA batteries? Tin foil.
Power is power, which means that if you can get the batteries to fit inside the battery compartment, you can get power to your devices. Ball the tin foil up to fill the rest of the space between the battery and the appliance. It won't run for as long, but it can still be handy in a pinch.
Find Your Own Thread
Thread comes from plants, and if you spot the right ones, you can even make your own rope. It won't be as good as the modern rope that you could have brought along but will be a big help if you have nothing else and need to fish, make a snare, or string a bow.
Make natural fibers out of palm leaves or, if you're in North America, from the Yucca plant. The plant has big fat leaves and barbed points that you can cut down to make some thread. Braid the thread to make a rope.
