The 5 things I would bring would be my phone, canned food, water, a gps, and a tent. I would bring my phone, because that way I could contact people if Im inan emergency or need something. Canned food so I have something to eat in case there is no other source of food around. Water so if I dint find clean water Im not forced to drink contaminated water and get sick later on. A gps so I always know where Im going and dont get lost, and a tent so I always have some king of refuge in case it rains.
