If you find out, let me know. In this part of Missouri, there are plenty, but most are on private property and the few on government land are sometimes rigged with cameras operated by the conservation department--to catch people destroying the caves environment, I imagine. I always wanted to search a few caves and I know of one which was used as a bar and restaurant when I was a kid. It burned down 20 years or so ago, and today is clearly marked off limits. This is one I plan to seek permission to search the mouth of. Problem though, many people used to party there after the bar burnt down. There was trash everywhere last time I was there. It is located on HWY 17, in Pulaski County, between Waynesville and Crocker Mo. If you are from Mo., whereabouts?
