What do you bring with you everywhere you go?
Are we talking outside of the norm such as my wallet, keys and phone? If so, then I always take an extra hair tie, a little sketch book and I always have a change of clothes in my trunk. Which, out of the three items is probably weird. But, I've found that they come in handy if I end up fixing a car and need to change my shirt or if I end up on a road trip for longer than I anticipate.
