Intrepid outdoor adventurers often hope to conquer a mountain peak or two in their lifetimes, but peakbaggers take mountain climbing to a whole new level. These goal-oriented extremists aren't necessarily aiming for the highest peaks — rather they're all about quantity (i.e., putting as many peaks "in the bag" as possible). Munro baggers, for instance, strive to climb all 283 Munros in the Scottish Highlands (the highest is 4,409 feet). To up the competition, some try to "bag" as many peaks as possible in a day or scale every peak in record time. Name a mountain range and there's probably a group of baggers — e.g., the Adirondack Forty-Sixers, the California Thirteeners, British Columbia's North Shore baggers, and even a group of fledgling New Zealand baggers.
