ASK A RANGER Q: Any special tricks for staying cool during summer?
A: Rangers always advise visitors to pack at least a gallon of water per person per day, use it to dampen their hats and shirts, and avoid the heat of the day, says ranger Dean Reese. "Sitting out the sunny hours is not practical for rangers, though, so we carry spray bottles--not a bad idea for hikers, either." Keep a spray bottle handy, and use it to spritz your face and neck often to aid in evaporative cooling. The few ounces can make hot days a little more comfy.
