We've never been asked that question. We love traveling, hiking, biking, Nat'l Parks, mostly dislike cities and hotels. If we were asked to calculate the cost we would also have to try to figure in the cost benefits of hiking, biking and all the exercise, stress relief we experience in the outdoors, relaxing at night by a fire, listening to rain on the 5th wheel roof at night, recalling all the memories we have given our children. Those items are significant when looking at health, wellness, motional and mental health. In other words - in our lives camping is priceless.
