INSTRUCTOR BIO: Jason Mifflin has owned and operated Hidden River Outfitters since June 2010. From homemade rafts to sea kayaks, Jason loves to be on the water in anything that floats. He spent much of his life paddling a canoe until he discovered kayaking about fourteen years ago. He appreciates both whitewater and flatwater kayaking for their respective exhilarating and relaxing qualities. Jason enjoys sharing his passion for being outdoors with others and reconnecting people with the rivers they often appreciate but never experience. Jason loves to get folks out on the water, regardless of their experience, and expose them to paddling. Also, as a native of Philadelphia, he enjoys recounting the history and function of many of the areas that we encounter on our tours.
