If you live in New England and have done any hiking along the Appalachian Trail, there's a good chance that the Appalachian Mountain Club and their volunteers are to thank. According to the AMC, "In a typical year, people like you volunteer approximately 18,000 hours building approximately 1,200 feet of bog bridging, completing about 1,000 feet of screewall, installing more than 300 feet of drainage, and building about 100 cairns. Local volunteers help maintain 1,500 miles of trails each year." Sign up now for 2010 Trail Crew Opportunities at Acadia National Park (Maine), the Berkshires (Massachusetts), the White Mountains (New Hampshire and Maine), Connecticut, the Delaware Water Gap (New Jersey & Pennsylvania), Baxter State Park (Maine), Cardigan Mountain (New Hampshire), and more. And if you volunteer, you'll get one of these fancy shirts.See the full 2010 Volunteer Vacations schedule or the full 2010 Work Party schedule.
