If you're looking for a chance to work off the pumpkin pie pounds this weekend, give thanks for the hale and hardy Urban Park Rangers. As part of their mission for New Yorkers to connect with nature, Urban Park Ranger hiking guides lead weekend hikes through NYC's public parks, and at 10am on November 26, you can participate in one of their most rigorous excursions: a two-hour tour of Van Cortlandt Park. Enjoy the autumn leaves and crisp, fresh air while learning tidbits about nature, NYC history and culture and the hidden treasures of this Bronx park, which also happens to be home to the United States' first public golf course.
