My husband and I enjoyed a delightful 2-day tour of the Black Hills in the company of Denny and Julie Gienger, who work tirelessly to understand their customer's interests, needs and abilities and tailor their tours to accommodate each customer's priorities. They are impressively knowledgeable about and sensitive to the history, customs, arts, social institutions and achievements of the indigenous and local populations. They share their knowledge comfortably and conversationally throughout the tour, easily anticipating and answering a wide range of questions. On the basis of previous travel/tour experiences in the United States and Europe, we recommend them without reservation as among the best of the best. They provide an exceptional experience in this beautiful, rugged part of our country.
