7. If generally departing from civilization, get a portable battery
This way you can selfie until the sun goes down, but still have some emergency charge in the event you sort of lose your friends in the mosh pit or need directions after getting super lost on a road trip. Carrying your charger’s a smart idea, but next generation, super-juiced external batteries like this one are even smarter, and allow you to carry up to eight full smartphone charges in your pocket. Never crouch, sadly tethered to an outlet until you can fiddle with your filters again. Now go forth and throw those elbows.
8. ...and get a mosquito bracelet
Bug spray is of course effective, but sticky, kind of smelly, and also easily forgotten. Throw a bug-repellant band on instead to keep the little buggers away. Your summer gets about fifty times more successful when you don’t have to stoop and scratch every five minutes because of the one time your forgot bug spray.
