Anyone can get in the game! The Photo scavenger hunt, in which you (working alone or in a group) seek out scenes or objects and capture them with your camera. No knowledge of any hunt location is required—all you need is a sharp mind and a good pair of shoes.
The hunt could be the centerpiece of your weekend, but also could serve as just a way to enhance your downtime as you wander from place to place, observing the natives in their natural habitat.
