NPR's Howard Berkes has part three of his series of the discovery and development of Kartchner Caverns State Park 50 miles from Tucson. The caves are located in Benson, Arizona, a small town getting ready for what may be a major tourist attraction when the caves open next month. Much of the development is controlled, but not all, and some residents think it's going to be the end of peace and quiet. Others are looking forward to the economic benefits that will accompany the tourist invasion. (8:24-8:44)
