Valley Forge National Park is a fun place to visit on foot, bike, or horseback. I enjoy mountain bike riding and took most of these photographs while bike riding with my sister along the multi-use trails that run throughout the park. Thanks, Amy, for holding my gear and for putting up with many stops during our ride!
